Graph the parent function $y=\sqrt{x}$. (refer to the attached image below) RECALL: The function $y=a\cdot f(x)$ involves either of the following transformations of the parent function $f(x)$: (i) a vertical stretch by a factor of $a$ if $a\gt0$, or (ii) a vertical compression if $0\lt a \lt 1$. The given function has $a=4$. This means that the graph of the given function involves a vertical stretch by a factor of $4$ of the parent function. Thus, to graph the given function, multiply each y-value of the parent function while retaining the x-value of each point.. Refer to the attached image in the answer part above.
