1. Graphing Quadratics Warm-up (IN) Solve by completing the square. 1. 2. 3. 4. Learning Objective: To use completing the square to rewrite a quadratic equation in vertex form, and then graph it.

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

3. 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

4. Learning Objective: To use completing the square to rewrite a quadratic equation in vertex form, and then graph it. y-int ________ x-int ________ vertex _______ domain _______ range ________ 7 and -3 (2,-25) Y-int -21

5. Learning Objective: To use completing the square to rewrite a quadratic equation in vertex form, and then graph it. y-int ________ x-int ________ vertex _______ domain _______ range ________ 4.4 and 1.6 (3,-4) Y-int 14
