Learning how to do these are the last things I need to learn for today.

Graph each function and its inverse.

1) F(x) = |x - 3| + 2

2) F(x) = (x + 2)2 + 3

(The small 2 represents power)

The first function is an inverse of the second and vice versa. Simply replace the 's in your function with 's to receive the inverse function.

Ah yes, sorry about that. :)

How would I solve the first problem?

recall that for absolute values you have to consider two cases, when what's inside absolute value signs is negative and when it is positive.

to find the inverse, we switch x and y and solve for y:

work on each piece separately.

For the first graph:

for

For inverse, switch x and y:

for

for (which is equivalent to )

now for the second graph:

for

For inverse, switch x and y:

for

for (which is equivalent to )

thus, putting these together we have:

the graph is below. the green is , the red is
