#### Answer

The graph and data table are shown below

#### Work Step by Step

To graph the given equation we calculate the domain and range and plot the points.
We calculate the range for the values x= -3, 0, 3
$y= -\frac{1}{3}x^{2}$
x=-3
$y= -\frac{1}{3}(-3)^{2}$
$y= -\frac{1}{3}(-3)(-3)$
$y= -3$
x=0
$y= -\frac{1}{3}(0)^{2}$
$y= -\frac{1}{3}(0)(0)$
$y= 0$
x=3
$y= -\frac{1}{3}(3)^{2}$
$y= -\frac{1}{3}(3)(3)$
$y= -3$
(-3,-3) (0,0) (3, -3)
We plot the points and connect the graph to get the final graph
