Answer
Plot $(-2, 2)$ then connect it to $(0, -4)$ and $(0, 0)$ using a smooth curve to form a circle.
Refer to the graph below.
Work Step by Step
In order to obtain the complete graph, we have to plot the points, symmetric to the given points already plotted on the graph.
The point, the symmetry with respect to the y-axis can be obtained if the point $(x,y)$ is on the graph, then $(-x,y)$ is also on the graph.
Here, if $(0,0)$ is on the graph, $(0,0)$ should also be on the graph.
Also, if $(2,2)$ is on the graph, $(-2,2)$ should also be on the graph.
Also, if $(0,4)$ is on the graph, $(0,4)$ should also be on the graph.
Plot the points, then connect them using a smooth curve to form a circle.
Refer to the graph above.
