$(3, -2)$

Recall that for a function and its inverse, the domain and the range are switched. This means that the point $(x,y)$ for the original function becomes the point $(y, x)$ for the inverse function. Thus, if the original function has the point $(-2, 3)$, we know that the new function will contain the point $(3, -2)$.
