So i know that to find an inverse equation you switch the x and y and then solve for y, but this question has me stumped.

"Suppose thath(x)andj(x)are inverses, and thath(3)= 7 andj(4)= 9. Find the following:

(a) j(7)

(b) h(9)

(c) h(j(13))"

I don't know if i am supposed to guess until i find such an equation or if there is a specific way to do it.

Please help me. I have been guessing for ours and i am no where near the right answer.

Thanks.
