Unit 10 - Graphing & Solving Quadratic Functions in Standard Form

Assignment Guide

Learning Targets:

1. I can graph a quadratic function in STANDARD form and label key features of a graph (max/min, intercepts, increasing/decreasing, end behavior, symmetry, positive/negative)
2. Using technology, I can find and explain the meaning of the solution to a non-linear equation.
3. I can identify, interpret, and use key features of a quadratic function. (modeling)
4. I can compare properties of two functions each represented in a different way (algebraically, graphically, numerically, verbally)
5. I can solve a quadratic equation using FACTORING and the ZERO PRODUCT PROPERTY.
6. I can solve a quadratic equation using the QUADRATIC FORMULA.
7. I can solve a quadratic equation by completing the square.
8. I can justify the method I use when solving a quadratic equation.
9. I can write an expression in equivalent forms by:
   • Factoring a quadratic expression to create the product of two binomials.
   • Adding, subtracting, and multiplying polynomials.
   • Rewriting a quadratic function in different forms (standard form, vertex form, intercept form).

I can distinguish a quadratic function from a linear or exponential function.
