    Finding the inverse of f(x) = 2x³ + 5x + 3 at x = 1

    Homework Statement Let f(x) = 2x^3 + 5x + 3 Find the inverse at f^-1(x) = 1 Homework Equations N/AThe 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...
