Graphing Quadratics Warm-up (IN) Solve by completing the square Learning Objective: To use completing the square to rewrite a quadratic equation in vertex form, and then graph it.

Notes Vertex form - Determines open up or down and fat or skinny Determines left or right Determines up or down Vertex (h,k)

Learning Objective: To use completing the square to rewrite a quadratic equation in vertex form, and then graph it. EX 1 – Solve the equation, state both intercepts, the vertex, D and R, create a table, then graph. y-int ________ x-int ________ vertex _______ domain _______ range ________ No solution! None! (-6,6) Y-int 42
