Find the equation in standard form that has a vertex (-4, 7) and goes through (5, 0).
**
Standard form of an equation for a parabola: y=A(x-h)^2+k, with (h,k) being the (x,y) coordinates of the vertex.
From given data:
0=A(5-(-4))^2+7
-7=A(5+4)^2=81A
A=-7/81
Equation:
y=(-7/81)(x+4)^2+7
see graph below as a visual check on equation
