i am having problems understanding this problem.
The given function $f$ is one-to-one. Find $f^{-1}$, find the point on the graph of $f^{-1}$ corresponding to the indicated value of $x$ in the domain of $f$.
$f(x) = 2x^3 + 2x; x = 2$

$f(x) = 2x^3 + 2x; x = 2$
$y = f(x) = 2x^3 + 2x$. But, $f(2) = 2\cdot 2^3 + 2\cdot 2 = 20$. Thus, $(20,2)$ is the point on the graph of $f^{-1}$.
