Big Ideas: The x-intercepts are the zeros of the function. The zeros hold meaning in real-world situations. Quadratics can have one or two real zeros. In this lesson, students will use vertex form to find the zeros of a quadratic function. This introduction to zeros as solutions to quadratic functions will lead to solving using factoring and graphing. Students will be able to recognize that the zeros are the x-intercepts of the graph and therefore have meaning in real-world situations. Students will understand that functions can have one or two real zeros for quadratics. Vocabulary: zeros of the function Special Materials: graphing calculator (optional)
