Write an equation for the parabola that has a vertex of (-1, 8) and goes through the point of (2, -10). A. =−2(+1)^2+8

B.=−18(−1)^2+18

C. =(+1)^2+8

D. =−2/9(−2)^2+10

y = - 6

step-by-step explanation:

given the point (- 2, y) lies on the graph then it is a solution of it's equation.

substitute x = - 2 into the equation for value of y

y = 3(- 2) = 3 × - 2 = - 6

the point on the graph is (- 2, 6)
