You can  put this solution on YOUR website! Find the standard equation of a parabola that has a vertical axis and satisfies the given conditions. 
vertex (0, −5), passing through (4, 27) 
** 
Standard form of equation for parabola: y=A(x-h)^2+k, (h,k)=(x,y) coordinates of vertex. 
For given parabola: 
equation:  
y=A(x-0)^2-5 
using coordinates of given point (4,27) 
27=A4^2-5=16A-5 
16A=32 
A=2 
Equation of given parabola: 
y=2x^2-5
