Answer 2

Oh, okay, inverses

Answer 3

So here are the steps to find the inverse,

1.) Set f(x) as y
2.) Switch the x and y variables
3.) Solve for y

Answer 4

Try that and I'll double check your work

Answer 5

ok what are the y variables?

Answer 6

Instead of f(x)=, you're going to change it to y= for step 1

Answer 7

ok got that now...

Answer 8

So then you switch the x and y variables
