Answer 1

For the inverse, you want to switch the places of x and y. Then solve for x.

Answer 2

Sorry. Let f(x) = y, then do that.

Answer 3

So you start off with y = 2x - 4. (Right?)

Answer 4

yes

Answer 5

i did 13 and 14

Answer 6

Switching the positions of x and y, we get x = 2y - 4. Now can you solve for x? (easy)

Answer 7

I need help with 15-17

Answer 8

Ooh. Okay then. (one moment.)

Answer 9

In 17, start out by factoring all the polynomials.

Answer 10

It's fairly easy. The numerators are all quadratics, but won't take you too long. On the bottom, one is prime and the other you can factor out 2 from.

Answer 11

Try factoring, and tell me what you get.

Answer 12

ok

Answer 13

And that's how you get your answer.

Answer 14

I got 2x+4/x-3

Answer 15

Is that right?
