**Title:** Quadratic Equation Grapher

**Description:**
Learn about graphing polynomials. The shape of the curve changes as the constants are adjusted. View the curves for the individual terms to see how they add to generate the polynomial curve.

**Standard(s): **

[MA2013] AL1 (9-12) 7: Interpret expressions that represent a quantity in terms of its context.* [A-SSE1]

[MA2013] AL1 (9-12) 9: Choose and produce an equivalent form of an expression to reveal and explain properties of the quantity represented by the expression.* [A-SSE3]

[MA2013] AL1 (9-12) 18: Solve quadratic equations in one variable. [A-REI4]

[MA2013] AL1 (9-12) 28: For a function that models a relationship between two quantities, interpret key features of graphs and tables in terms of the quantities, and sketch graphs showing key features given a verbal description of the relationship. *Key features include intercepts; intervals where the function is increasing, decreasing, positive, or negative; relative maximums and minimums; symmetries; end behavior; and periodicity.** [F-IF4]

[MA2013] AL1 (9-12) 31: Graph functions expressed symbolically and show key features of the graph, by hand in simple cases and using technology for more complicated cases.* [F-IF7]
