  1. Algebra 1: 10.3 Graphing Quadratics Learning Task/Big Idea: Students will learn how to find roots(x-intercepts) of a quadratic function and use the roots to graph the parabola.

  2. Notes: • When you solve a quadratic equation your solutions are the _______________ of the graph. • Another word for the solutions of a quadratic equation is _____________________. • We can solve the quadratic equation and use the solutions to help graph the equation. • We also need to know if the graph opens UP or DOWN and the Vertex of the parabola.

  3. Ex1: Solve, determine whether the parabola opens up or down and find the vertex.
