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


This concept will more into detail for graphing quadratics.in unit B, you only graph the quadratic using the shifts of the parent function. now you'll go a step further to make the graph more accurate and detailed by identifying the vertex, x and y-intercepts, and the axis of symmetry.
     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.
