 find the vertex equation form, f(x) = a(x-h)2 + k, for a parabola that passes through the point (-6,9) and has (-5,8) as its vertex. what is the standard form of the equation?

a)the vertex form of the equation is f(x) = (x + 5)2 + 8. the standard form of the equation is f(x) = x2 + 10x + 33.
b)the vertex form of the equation is f(x) = (x - 5)2 + 8. the standard form of the equation is f(x) = x2 - 10x + 33.
c)the vertex form of the equation is f(x) = −(x + 5)2 + 8. the standard form of the equation is f(x) = x2 - 10x + 33.
d)the vertex form of the equation is f(x) = (x + 5)2 - 8. the standard form of the equation is f(x) = −x2 + 10x - 33.
