Unit 9 - Graphing & Solving Quadratic Functions in Vertex and Intercept Form

Assignment Guide

Learning Targets:

1. I can graph a quadratic function in any form by making a table of values.
2. I can graph a quadratic function in VERTEX form and label key features of a graph (max/min, intercepts, increasing/decreasing, end behavior, symmetry, positive/negative)
3. I can graph a quadratic function in INTERCEPT form and label key features of a graph (max/min, intercepts, increasing/decreasing, end behavior, symmetry, positive/negative)
4. I can recognize two quadratic functions as being equivalent or not equivalent.
5. Using technology, I can find, and explain the meaning of, the solution to a system of perhaps non-linear equations.
6. I can compare properties of two functions each represented in a different way (algebraically, graphically, numerically, verbally)
7. I can solve a quadratic equation using SQUARE ROOTS.
8. I can solve a quadratic equation using the ZERO PRODUCT PROPERTY.
9. I can write an expression in equivalent forms by:
   • Multiplying two binomials to create a quadratic expression.
   • Rewriting a quadratic function in different forms (standard form, vertex form, intercept form).
