Answer

Point = $(8, 16)$

Work Step by Step

Given that point $(8, 12)$ is on the graph of $y = f(x)$ and it can be seen that the graph of $y = f(x) + 4$ is the vertical translation of the graph of $y = f(x)$ up by 4 units, one point on the graph of $y = f(x) + 4$ will be $(8, 16)$ because for every point $(x, y)$ on the graph of $y = f(x)$, there will be a corresponding point $(x, y+4)$ on the graph of $y = f(x) + 4$ .
