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= -2,-1. 0, 1, 2 $y= -4x^{2}$ x=-2 $y= -4(-2)^{2}$ $y= -4(-2)(-2)$ $y= -16$ x=-1 $y= -4(-1)^{2}$ $y= -4(-1)(-1)$ $y= -4$ x=0 $y= -4(0)^{2}$ $y= -4(0)(0)$ $y= 0$ x=1 $y= -4(1)^{2}$ $y= -4(1)(1)$ $y= -4$ x=-2 $y= -4(2)^{2}$ $y= -4(2)(2)$ $y= -16$ (-2,-16) (-1,-4) (0,0) (1, -4) (2, -16)
