1. Algebra 2 Ch.5 Notes Page 30 P 30 5-1 Modeling Data with Quadratic Equations

2. Quadratic Functions Standard Form:y = ax 2 + bx + c f(x) = ax 2 + bx + c ax 2 + bx + c Quadratic Term Linear TermConstant a, b, and c are Numbers

3. Shape - Parabola Axis (Line) of Symmetry Vertical Line through the Vertex x = Number (?) Vertex - Hightest/Lowest Point Max or Min Graphs of Quadratic Functions y = x 2

4. Points on a Parabola Points are Symmetric about the Axis (Line) of Symmetry Find P' and Q' Find Vertex Find Line of Symm

5. Fitting a Quadratic Functions to 3 Points Find Equation for the Given Points Substitute into y = ax 2 + bx + c 3 = a(2) 2 + b(2) + c = 4a + 2b + 1c = 3 13 = a(3) 2 + b(3) + c = 9a + 3b + 1c = 13 29 = a(4) 2 + b(4) + c = 16a + 4b + 1c = 29 Use a Solving Method from Ch.3 or Matricies Substitution/Elimination/Matricies
