Answer
Refer to the blue graph below.
Work Step by Step
The parent function of $y=2\sqrt{x}$ is $y=\sqrt{x}$.
RECALL:
The graph of $y=c \cdot f(x)$ involves a vertical stretch by a factor of $c$ of the parent function $y=f(x)$.
The given function has $c=2$.
Thus, its graph involves a vertical stretch by a factor of $2$ of the function $y=\sqrt{x}$.
To graph the given function, perform the following steps:
(1) Graph the parent function $y=\sqrt{x}$. Refer to the black graph below.
(2) Stretch vertically the parent function by a factor of the $2$ to obtain the graph of $y=2\sqrt{x}$. Refer to the blue graph below.
