1 Using a 3 Variable System to find a Quadratic Equation

2 Writing a Contextual 3 Variable System Suppose the graph of a quadratic function passes through the points (1,0), (2,5), and (3,12). Algebraically find the quadratic equation. 2. Substitute each Point into the Equation: 1. Use the Standard Quadratic Form: 3. Simplify the Equations: y x

3 Solving a Contextual 3 Variable System Solve the system: 2. Solve the new system 3. Solve for the 3 rd Variable 4. Subsititue into the Standard Form: + 1. Use Elimination to write a 2-Variable System Eliminate the “c” first! ++ 1 2 3 1 2 1 3
