I wrote this 12-question circuit for my algebra one students, though it definitely gets challenging towards the end. I could definitely see algebra 2 or precalculus students using this circuit. Students will mainly be evaluating piecewise functions from their equations. In a few problems they will find the larger value or solve an equation such as f(x) = 3. The answers are embedded in the circuit -- it is how the students move from one question to the next. For this reason there is no answer key provided. The teacher should quickly work the circuit first to decide best how to use it with their students.
My colleagues and I check our work very carefully, but if you suspect there is an error, or if you get stuck, please email me at email@example.com
