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)
