Graph the equation y=−x²−8x−15 on the accompanying set of axes. You must plot 5 points including the roots and the vertex.

Step-by-step explanation:

y intercept x = 0

y = −0² − 8(0) − 15 = (0, -15)

x intercepts, factors = 0

y =−x² − 8x − 15  = (-x - 5)(x + 3)  (-5, 0) (-3, 0)

vertex is half way between the zeros

y =−(-4)² − 8(-4) − 15

(-4, 1)

Choose any other x you like

y =−(-1)² − 8(-1) − 15 = -8

(-1, -8)
