Quadratic Function - Standard Form vs. Graphing Form

This sketch allows you to control a quadratic function by adjusting the coefficients in the standards form equation: [math]f(x) = ax^2 + bx + c[/math]. Try using this information to Complete the Square and find the Graphing Form of the quadratic (then check your answer by clicking the check box).

Complete the Square to find the Graphing Form and check your answer. Created by Kathryn Brenneman for MA 111 at NC State University, Fall 2012. (This Worksheet was corrected and adapted from: [url]http://www.geogebratube.org/material/show/id/2841[/url])
