Write Quadratic Functions and Models

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)
