Step-by-step explanation:
Oh that’s on safari i just looked it up lol. go check it out. sorry if it’s not there for u. but i didn’t feel like typing that much
The only that has the shape of the one below.
y = -4(x^3 + 7x^2+8x - 16)
Let x = 1
y = - 4(1 + 7 + 8 - 16)
y = 0
y = -4(x -1)(x^2 + 8x + 16)
y = -4(x - 1)(x + 4)^2
