This 12-question circuit requires the use of technology. Students will perform regressions for linear, quadratic, cubic, and quartic tables of values. The technology will display the answers in expanded form, but most of the answers on the circuit are in factored form, so students need to start making connections with the zeros of functions in order to advance in the circuit.
The circuit contains all of the answers since that is the way students check their work and stay engaged with the practice. In other words, no answer key is needed. All the teacher needs to do is work the circuit him or herself first to see how the ideas unfold. Your students will love this format and beg for more circuits.
