Question

I really need some help. I need to find the inverse of this equation in the picture below. Thanks!

Answer 1

y=81x^4+648x^3+1944x^2+2592x+1289

Explanation:

1. Interchange x and y.

• y=\frac{\sqrt[4]{x+7}}{3}-2

• x=\frac{\sqrt[4]{y+7}}{3}-2

2. Then solve x=\frac{\sqrt[4]{y+7}}{3}-2 for y.

3. y=81x^4+648x^3+1944x^2+2592x+1289

I hope this helps.
