Answer

The graph and data table are shown below:
1516766214

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= -1, -2, -3 $y= -2x^{2} - 8x - 3$ x=-1 $y= -2x^{2} - 8x - 3$ $y= -2(-1)^{2} - 8(-1) - 3$ $y= 3$ x=-2 $y= -2x^{2} - 8x - 3$ $y= -2(-2)^{2} - 8(-2) - 3$ $y= 5$ x=-3 $y= -2x^{2} - 8x - 3$ $y= -2(-3)^{2} - 8(-3) - 3$ $y= 3$ We plot the points and connect the graph to get the final graph (-1,3) (-2,5) (-3,3)
