Instructional Ideas

• Have learners work in groups to graph the sets of functions

Classroom Considerations

• Pupils should know how to adjust the window of the graphing calculator
• Note that the resource does not actually teach how to factor quadratics

Pros

• Includes handouts

Cons

• Does not include quadratics with just one root
