Graphing Functions Teacher Resources

Graph quadratic functions that are given in the vertex form. Students receive immediate feedback and have the opportunity to try questions repeatedly, watch a video or receive hints.

[Free Registration/Login may be required to access all resource tools.] Students learn how to graph linear equations. Students examine guided notes, review guided practice, watch instructional videos and attempt practice problems.

A function is a relation that assigns exactly one value of the dependent variable to each value of the independent variable. When a function is graphed, a vertical line can pass through the graph and touch only one point.

In this activity, students use the graphing capabilities of the TI-86 to graph different functions. They develop capabilities for analyzing a graph Using several of the items contained in the GRAPH MATH menu.

In this Lesson Concept we use whole-class participation in the Activity Center to cultivate students understanding of how the graph of a basic function can vary through the change of a parameter. The classroom-group environment can...
