Let f(x) = 2x^3 + 5x + 3

Find the inverse at f^-1(x) = 1

2. Relevant equations

N/A

3. The attempt at a solution

The only way that I know how to solve inverses is by solving for X, then replacing it by Y. Then I supposed I would sub 1 into the inverted polynomial. However I'm not sure how to solve for X.

My attempt:

y - 3 = 2x^3 + 5x

(y - 3)/x = x(2x^2 + 5)

Then, hopelessness. Any info will be extremely helpful for my test this Friday. Thank you.
