X/y intercept for translations of f(x)

  • Thread starter roger
  • Start date
In summary, the conversation discusses various transformations of a given function, including af(x), f(ax), -f(x), and f(-x), and their effects on the x intercept, y intercept, and vertex of the function's graph. It is noted that the specific changes depend on the function and it is suggested to convert the function into transformation/vertex form to better understand the transformations.

Hello

please can you guys help me on this :

f(x) = x^2 + 2x + 2

af(x)=
f(ax)=
-f(x)=
f(-x)=


In each of the cases above, I wanted to know given a function, does the graph of it change in terms of the x intercept , y intercept and vertex ?

Does it depend on the particular function or not ?


Thanks in advance.

roger

Why don't you first change that equation into transformation/vertex form
[tex]
f(x) = (x-h)^2 + k
[/tex]

The make up numbers for a and see how it changes.

af(x) represent the graph of f(x) is enlarged a times of the oringinal to the y-axis.
 

What is the x-intercept?

The x-intercept is the point where a graph crosses the x-axis. It is the value of x when the graph intersects the x-axis, and the y-value at this point is always 0.

What is the y-intercept?

The y-intercept is the point where a graph crosses the y-axis. It is the value of y when the graph intersects the y-axis, and the x-value at this point is always 0.

How do you find the x-intercept?

The x-intercept can be found by setting y = 0 in the equation of the graph and solving for x. This will give you the x-value at the point where the graph crosses the x-axis.

How do you find the y-intercept?

The y-intercept can be found by setting x = 0 in the equation of the graph and solving for y. This will give you the y-value at the point where the graph crosses the y-axis.

What is the significance of the x/y intercept for translations of f(x)?

The x and y intercepts are important in translations of f(x) because they help us determine the position of the graph on the coordinate plane. The x-intercept represents the horizontal translation of the graph, while the y-intercept represents the vertical translation. By knowing the values of these intercepts, we can accurately translate the graph to different positions on the coordinate plane.
