    correct, where (h,k) is the vertex

    So first of all, lets plug in the vertex into this equation. :)

    vertex is (0,0) in the form of (h,k) that means h=0 and k=0

    so if we plug that into the vertex form we get: \(\sf\Large y=a(x-h)^2+k\) \(\sf\Large y=a(x-0)^2+0\) \(\sf\Large y=a(x)^2\)

    Now plug in the points (2,-2) to solve for 'a'
