How do I do the inverse function of...
-----
Each problem involves 2 steps:
1st: Interchange x and y
2nd: Solve for "y":
-----------------------------------------
1. y=3(x)^5
x = 3y^5
y = (x/3)^(1/5)
---------------------------
2. y=4-x/8
x = 4-y/8
-y = 8x-4
y = 4-8x
---------------------------
3. y=3-(x/4)
x = 3-(y/4)
(y/4) = 3-x
y = 12-4x
---------------------------
4. y = 2(x-1)^3-3
x = 2(y-1)^3-3
(y-1)^3 = (x+3)/2
y = [(x+3)/2]^(1/3)+1
---------------------------------------------
