Answer
Point = $(8, 48)$
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 $y = 4 f(x)$ is the vertical stretching of the graph of $y = f(x)$ by $4$ times,
One point on the graph of $y = 4 f(x)$ will be $(8, 48)$ because for every corresponding $x$-values on the graph of $y = f(x)$, the $y$-values of the graph of $y = 4 f(x)$ are each $4$ times those of $y = f(x)$.
