This is a unit that formalizes the definition of functions. Students will connect the idea of mathematical relationships to the concept of functions. With a mix of direct instruction, guided notes with procedural practice, and individual practice, this unit will ground students in the concept and provide a deep understanding of its usefulness.

Students have mastered solving equations and looking at solutions graphically. This unit is an extension and will have students investigate how to find to two equations. This unit will utilize investigate and exploration,  with some direct instruction, to solidify the process and procedures to finding and identifying solutions to systems.
