The general function is sometimes using this form of the equation is difficult to graph but you can change it to standard form

1. Take out what’s common (if possible).

2. Factor

3. Complete

$latex y=2(x+1)^2-4

This form of the equation gives you more then enough information to graph.

P and q are the vertex points (be careful because the p sign will switch from pos to neg or neg to pos), knowing the vertex gives you the axis of symmetry and where the graph starts. A tells you whether the graph will be opening up or down and if it’s stretched or compressed.
