The two key points of a parabola are the (x,y) coordinates of the vertex.
To determine these coordinates, equation of the parabola must be in standard form: y=A(x-h)^2+k, (h,k) being the (x,y) coordinates of the vertex. If not in this form, the first step is to complete the square. Other useful points for the graph are the x and y intercepts. Set x=0, to find y-intercepts, and set y=0, to find x-intercepts.
