Question

Please explain The polynomial passes through the point of (-4, -8) and has end behavior of down, down. The

intercepts of the graph are x = -2, 1, 2, and 4.

Answer 1

The y-value of the point (4, 8) is (obviously) 8. Since the line has a slope of zero, everywhere on the line will have a y-value of 8. So the equation of the line is y = 8. The x-value can be any number, but the y-value will always be 8
