To find the inverse, what would you have to do to f(x) to get back to x?
Well, to get f(x) you cubed x, then added 7. So reverse that:
Subtract 7, then
take the cube root.
F-^1(x)=(x-7)^1/3
Use that process and you'll get these fine.

The domain and range of values of x are d values of x for which d answer is not 0. So equate the funtion to 0 and get ur number. afterfinding the inverse equate wat u get 2 0 to find the domain and the range of d inverse. I hope dis helps.
