Pay attention to start in standard form (f(x)=ax^2+bx+c) then complete the square to put the parent function form in f(x)=a(x-h)^2+k. The graph will include 2 to 4 points, those points will be the vertex, the x and y-intercepts, and the axis. To get the vertex its the (h,k) of the parent function, h will always be the opposite ex. h=2 it will be -2 for the vertex.

SP#1: Unit E Concept 1: Identifying x-intercepts, y-intercepts, vertex (max/min), axis of quadratics and graphing them. Quadratics in standard form
