Match each function with the expression representing its inverse function.
1. y = x - 4
2. g(x) = -0.5x
3. k(x) = x
4. p(x) = x + 4
5. h(x) = 4x
6. f(x) = x/2

x+4
x
0.25x
-2x
x - 4
2x

**Tip: inverse means opposite**

1.) The opposite of '+' is '-' so the opposite of "x - 4" is "x + 4."

2.) The opposite of -0.5x (or -1/2) is positive 2x (to get the opposite of a fraction you switch the nominator and the denominator, and the sign, if a fraction has 1 as the nominator when you switch them there is no need to write it, for example; 1/3 would be 3/1 which is 3.)

3.) I think you made a typo...but hopefully you get the my point so far.

4.) The inverse of "x + 4" is "x - 4."

5.) The inverse of "4x" should be "-0.25x," I think there may have been a typo here too.

6.) The inverse of "x/2" is "-2x."
