1. Topics: Standard and Vertex form of a Quadratic Function Finding Key Features of a Quadratic algebraically and graphically. Graphing Quadratics

2. Several key features can be determined from the standard form: * Concavity * Vertex (minimum or maximum) * Axis of Symmetry * y-intercepts * X-intercepts * ALL QUADRATICS ARE A PARABOLA!

3. Function Is it Quadratic? (circle one) If Quadratic, what is the Concavity? (circle one) Yes NoUp Down Yes NoUp Down Yes NoUp Down Yes NoUp Down If a > 0, the parabola is concave up. If a < 0, the parabola is concave down.

4. Function Vertex (show work) Maximum or Minimum? (circle one) Max Min

5. FunctionVertex Maximum or Minimum? (circle one) Max Min

7. Steps 1. Find the vertex 2. Make a table of values centered around the vertex. (At least 5 points) 3. Graph on a coordinate plane.

8. Function X-intercept(s) 2 nd, TRACE, #2 Y-intercept TRACE, 0, ENTER
