Question

Match each function with the expression representing its inverse function.

1. y = x - 4 x + 4
2. g(x) = -0.5x -2x
3. k(x) = x x - 4
4. p(x) = x + 4 2x
5. h(x) = 4x 0.25x
6. ƒ(x) = x/2 x

Answer 1

hey i just need a little help matching these

Answer 2

do you know how to find an inverse function?

Answer 3

no i cant remember

Answer 4

its y = f(x)
right?

Answer 5

okay basically, you start off with a function.
Then you switch around the x values to y values and vice versa. Then solve for y.

E.g. in your first function, we have:
y = x - 4
To find the inverse, change the y to an x and the x to a y. So,
x = y - 4
Now we solve for y by adding 4 to both sides. Therefore,
x + 4 = y
Therefore your ORIGINAL function was y = x - 4 , the INVERSE function is y = x + 4

Answer 6

make sense??

Answer 7

oh so you pretty much switch then solve

Answer 8

yep :)
and you do the same for all of them ^_^
