Answer
Refer to the graph below.
Work Step by Step
Create a table of values by assigning values to $x$ then solve fot the corresponding value of $y$ for each $x$ to obtain:
\begin{array}{ccc}
&x &y &(x, y)\\
&0 &0 &(0, 0)\\
&2 &2\sqrt2&(2, 2\sqrt2)\\
&4 &2 &(4, 2)\\
&8 &2\sqrt2 &(8, 2\sqrt2)\\
&16 &4 &(16,4)\\
\end{array}
Plot the points then connect them using a smooth curve.
Refer to the graph above.
