The general equation of parabola is :
[tex]\begin{gathered} y=a(x-h)^2+k \\ \text{where}(h,k)\text{ are the vertex of the curve} \end{gathered}[/tex]
a > 0, that means the curve is upward
x intercept and y intercept at 4
x intercept at 4 meanse : x = 4
Coordinates are ( 4,0)
y intercept at 4 meanse y = 4
Coordinates are : (x,y) =(0,4)
