Suppose f(x) is a piecewise function defined as follows
f(x) = 2x^2+2 ---- > x < 1
= 2x^2 - 3x ----- > 1 ≤ x ≤ 2
= 2 - (6/x) ----- > x > 2
Graph f(x) for 0 ≤ x ≤ 3Find the left and right hand limits of f(x) as x approaches 1 and as x approaches...
Homework Statement
Sketch a graph of a function that satisfies the stated conditions:
lim f(x) [as x approaches 2) = 3 and f(2) = 4.
Homework Equations
N/A
The Attempt at a Solution
I know that the graph looks like an absolute value function (because the professor told me), but...
so can I put an absolute value inside another absolute value? The function would look something like this?
I x-1I -1 I
Would it be valid to take the y values from the original function and plug them back into the original function?
Homework Statement
f(x) = (arctan(ln(sqrtx - 1)))^3
Homework Equations
domain of arctan: all real numbers
range of arctan: -∏/2, ∏/2
The Attempt at a Solution
I know that domain is x>0 when x ≠ 1, because I need a positive number to go under the radical and the natural log of 0 is...
Homework Statement
Suppose f is the function defined by f(x) = l x-1 l Sketch the graph of y = f(f(x))
Homework Equations
The Attempt at a Solution
It's not so much sketching the graph that is the problem as much as it is figuring out how to set up the equations. How do I put an...
