Question

What is the inverse of the function y = 2(x + 1)³?

Answer 1

`√(x)`
`\sqrt[3]{1/2(x)}` - 1 = y

Explanation:

Inverse: swap x and y

y =2(x+1)^3

x = 2(y + 1)^3

now put it in a y = mx + b form

x = 2(y + 1)^3

1/2(X) = (y+1)^3

`√(x)`
`\sqrt[3]{1/2(x)}`= y + 1

`√(x)`
`\sqrt[3]{1/2(x)}` - 1 = y
