Checking Inverses with Function Composition

This is a riddle worksheet in which students use an answer bank to solve a (slightly cheesy) joke. They like this activity because it makes the math meaningful and FUN. Teachers like it because the answer bank gives students a tool to self-assess.

Because of the answer bank for students and answer sheet for teachers, this activity is great for home, school and students with special needs. Great for warm-ups, great for use with a substitute.

In this riddle worksheet, students check if two given functions are inverses by plugging one into the other and checking if they cancel to x or if f(g(x)) = x = g(f(x)).

This activity requires NO PREP, answer sheets included.
