Engage your students with this 20-question circuit on domain and range! Once you and your students try a circuit, you will be hooked! This circuit involves piecewise, composite, rational, quadratic, square root, cube root, trig, exponential and log functions. It seems simple (in each case students are given a function and then asked for the domain OR the range). But, all of the answers are very similar AND in interval notation so the students really have to understand the behavior(s) of vari
