straight line AB located at number line ( coordinate x ) , point A located on a number of number line, point B located on any number of number line , that this is a function of ?
yes - A and B are points on the same number lineRUber said:Not sure I understand your question. A and B are points on the same number line? Where is x? What are you trying to find?
HallsofIvy said:If A is a fixed point on the number line and B a variable point, then, for example, the distance between them is a function of A, f(A). .
|x1 - x2| gives you the distance between two numbers on the x-axis.point said:first solution
A=x1, B=x2 , AB=y ,y=|x _1-x_2|
?point said:second solution
A=x , B=y1=f(x) , AB=y2, y_2=|x-f(x)|
Without more information, I don't think we'll be able to help you.point said:continuation - dynamic graphics, static graphics, partial graph y=|a-x| ?
native speaker of Serbian , that you read the google translator in EnglishMark44 said:I suspect that you are not a native speaker of English. What you have written is very unclear, so it's hard to comprehend what you're trying to do.
.
AB=|A-B| or y=|x1-x2|, since the variables segment here and point the variable I used bookmarks (x ,y)Mark44 said:Your notation is nonstandard. AB is normally used to indicate the line segment between points A and B. To represent the length of this line segment, you could write |AB| or length(AB).
.
the first solution is provided with two variables (x_1 , x_2 )Mark44 said:Second solution of what?
This is extremely unclear. You have way too many variables here: A, B, x, f(x), y1, y2
.
Points are normally written in this order (x, y).point said:y = a-x
The graph of the current solution:
x-coordinate represents all real numbers, when solved function we have two numbers (y, x) ,
I'm having a hard time understanding what you're trying to say here. A coordinate is one of the numbers in an ordered pair. For example, the point (2, 1) has an x-coordinate (2) and a y-coordinate (1). It doesn't make any sense to talk about something being perpendicular to the x-coordinate. A line can be parallel to the y-axis or to the line x = 2.point said:introduces the new coordinates y perpendicular to the x-coordinate and cut the number 0 (plane), the number of y is transferred to the y-coordinate , line (which is parallel to the y-coordinate, and on it is a point that is the number x) is cut from the line (which is parallel to the x-coordinate and it is a point that is the number y) gets the point in the plane (x, y)
which means that the point (x, y) on the x-coordinate of the mapped into a point in the plane (x, y) points are merged to obtain a graph
The graph of this function has a V shape. Wherever a - x ≥ 0, the graph of y = |a - x| is identical to the graph of y = a - x. Where a - x < 0, the graph of y = |a - x| is the reflection across the x-axis of the graph of y = a - x.point said:y = | a-x |
The number a is considered to be a parameter. It might not be known, but it doesn't change, unlike x and y, which are variable.point said:Graph of my solution:
x-coordinate represents all real numbers, when solved function we have three numbers (a, y, x)
In the vigilink graph (which takes a very long time to load), you are graphing y = |3 - x|. The V shape of this graph is what I was talking about above.point said:, introduces the new coordinates y perpendicular to the x-coordinate and cut the number 0 (plane), the number of y is transferred to the y-coordinates, lines (the first parallel to the y-coordinate, and on it is a point that is the number a , the second is parallel to the y-coordinate, and on it is a point that is the number x) is cut from the line (which is parallel to the x-coordinate and it is the point which is also the number y) gave the points in the plane (x, y) and (a, y) of the connecting point is obtained straight line
which means that the points (a, x, y) on the x-coordinates are mapped onto the straight line AB in the plane (A (x, y) B (s, y)), the straight line are merged to obtain the graph of

you're wrong x ≥ 0 ( should x ≥ a ) , x < 0 ( should x < a )Mark44 said:The graph of this function has a V shape. Wherever a - x ≥ 0, the graph of y = |a - x| is identical to the graph of y = a - x. Where a - x < 0, the graph of y = |a - x| is the reflection across the x-axis of the graph of y = a - x.
straight line from the x-coordinates of the projected area in the plane, and needs two points ( a ,x ) and the distance between them ( y )Mark44 said:The number a is considered to be a parameter. It might not be known, but it doesn't change, unlike x and y, which are variable.

I didn't write x ≥ 0. Notice that I wrote a - x ≥ 0 and a - x < 0. The first inequality is equivalent to a ≥ x. The second inequality is equivalent to a < x.point said:you're wrong x ≥ 0 ( should x ≥ a ) , x < 0 ( should x < a )

The pictures aren't that helpful, but what's worse is that the mathematics description you're writing doesn't make any sense. In the first drawing there are two red line segments. The upper line segment can be described as {(x, y) : 1 ≤ x ≤ 3, y = 2}. The lower segment can be described in a similar manner.point said:I'll explain using pictures
x=1 , red color straight , x- coordinates ( |3-1| , |3-x| ) is mapped to plane (˙y=|3-x| , |3-1|=2 )

Here's how I would write it:point said:On the x-coordinate, there is straight AB, point A is fixed on the x-coordinate, point B is located at any point x-coordinates, to describe this function.
Solutions : A=a , B=x , AB=y
Choice a gives the distance from A to B, and will be positive unless a = x. Choice b is the negative of the distance from A to B.point said:a) y=|a-x|
b) y=-|a-x|
These two are the negatives of one another. If x > a, then a - x < 0, or equivalently, x - a > 0.point said:c) y=a-x
d) y=x-a
No.point said:a) y=|2-x|

No, again. The equation y = -|2 - x| is the two lines that make up the upper boundary. What you show in red is the graph of the inequality ##y \le -|2 - x|##.point said:b) y=-|2-x|

No again, and this graph is not a surface -- it's a straight line. This equation represents only a straight line, not a two-dimensional region. The line passes through (0, 2) on the y-axis and (2, 0) on the x-axis.point said:c) y=2-x
graph, the red surface
No again. This is only a line, not a two-dimensional region. It passes through (0, -2) and (2, 0).point said:
You seem to have a misunderstanding about what the graphs of equations look like. Any equation of the form Ax + By = C represents a straight line, not a two-dimensional region. A linear inequality, such as Ax + By ≥ C or Ax + By ≤ C does represent a two-dimensional region, a half plane.point said:e) y=\{|2-x|\}\cup\{-|2-x|\} or y=\{2-x\}\cup\{x-2\}

Until you understand these basic concepts of analytic geometry, it will be hard to understand what you are trying to do.
The "current rules" of mathematics are what we have to work with. New rules would come under the heading of "personal theory," which is not allowed here.point said:do not weigh the current rules of mathematics
Your explanations are incomprehensible, at least by me and one other mentor.point said:I explained the rules
