An applicable equation of a vertical parabola in vertex form is:
y-k = a(x-h)^2
Let x=2, y=4, h=-1 and k=-1, where (h,k) is the vertex. Then,
4-(-1) = a(2-[-1])^2, which becomes 5 = a(9). Therefore, a = 5/9, and the
equation of the parabola is
y+1 = (5/9)(x+1)
Answer:
c.9

Answer:
-30
Step-by-step explanation:
2*5 is 10
10*-3 is -30
(X + 4)(X^2 - 1) = x^3 + 4x^2 - x - 4
