Answer
Refer to the graph below.
Work Step by Step
In order to sketch the graph, we should first look at the $(x,y)$ coordinates that satisfy the equation.
We can get some of these points by assinging values tio $x$ then slving for the corresponding value of $y$ for each value of $x$.
If $x=0$, then $y=\sqrt0=0$.
Thus, $(0,0)$ is on the graph.
If $x=1$, then $y=\sqrt1=1$.
Thus, $(1,1)$ is on the graph.
If $x=4$, then $y=\sqrt4=2$.
Thus, $(4,2)$ is on the graph.
If $x=9$, then $y=\sqrt9=3$.
Thus, $(9,3)$ is on the graph.
Plot these points and connect them using a smooth curve to complete the graph,
Refer to the graph above.
