1. Write Quadratic Functions and Models

2. Writing a Quadratic Function in Vertex Form:
Remember:
Vertex form is y = a(x-h)2+k
You will be given the vertex, (h, k) and a point (x, y).
Step 1: Start with y = a(x-h)2+k
Step 2: Substitute in y, x, h, and k
Step 3: Solve for the a value
Step 4: Write the equation in vertex form (the only variables should be x and y)
