What is the equation of the parabola that has its vertex at (8,-1) and a y-intercept of (0,-17)? O A) y=1/x-812 - 1 B) y = -1/4(X + 8)2 1 OC) y = -1/4(x - 2)2 - 1 OD) y= -1/4(x - 3)2 + 1

5x+40

5(x + 8)

7x - 49

7(x - 7)

18x + 9

9(2x + 1)

15x - 10

5(3x - 2)

step-by-step explanation:

for number one all you have to do is factor 5 out of 5x + 40

for number 2 factor 7 out of 7x - 49

for number three factor 9 out of 18x + 9

for number four factor 5 out of 15x - 10
