If the point $(3,6)$ is on the graph of $y=g(x)$, and $h(x)=(g(x))^2$ for all $x$, then there is one point that must be on the graph of $y=h(x)$. What is the sum of the coordinates of that point?
The point that must be on the graph of y = h(x) is (9,12), so the answer is 9 + 12 = 21.
The real answer is 39 tho
