Your students will enjoy practicing finding zeros (x-intercepts) of linear, quadratic, cubic functions. Students must hunt for their answer(s) in order to advance in this circuit. The circuit presents 24 problems in a progressive manner (the exercises become tougher as the students advance). Perfect for Algebra I or Algebra II level students. The circuit can be worked without technology because all of the functions can be factored over the real number system -- or they are easily recognizable shifts. There are a few surprises too. You will have fun watching your students work and discuss. NOTE: This circuit can be found as one of five circuits in the CCSS Algebra I bundle.
