2. Vocabulary Parabola A curved 2 nd degree function.

3. Vocabulary Vertex The maximum or minimum point of a parabola.

4. #1 Graph the Following Quadratic Function x y 7 7 -7

5. Vocabulary x-intercepts The point(s) at which the graph crosses the x-axis; when solving algebraically, set the range equal to 0.

6. #2 Find the x-intercepts of the Parabola x y 7 7 -7

7. Vocabulary Axis of Symmetry The fold of the graph so the two sides of the parabola coincide.
