We're given f of x is equal to the cube root of x plus 10.
00:07
And then for part a, we want to find f inverse of x.
00:14
Well, that means that we set x, where this is y is cube root of x plus 10.
00:22
Then we reverse the role of x and y.
00:25
So i get x is the cube root of y plus 10.
00:30
And then we want to solve this for y to find f inverse.
00:36
Well, then x minus 10 is going to be the cube root of y, and that means then taking the third power of both sides, we get x minus 10 to the third is the cube root of y to the third, which is y.
00:53
So f inverse of x, which is y, is equal to x minus 10 to the third.
01:05
And then graph f and f inverse in the same coordinate system.

Well, let's see here...
