Students will practice using function notation and evaluating functions with this “Triples” Activity. Not only will students practice evaluating functions, but they will also practice solving for x given f(x).

There are 24 total cards to solve. Once students have solved all cards, they look for the matching “triples”. There will be 8 sets of three cards, each having the same answer. Students can work on their own or with a partner to match the cards. They can show their work directly on the back of the card, or on a separate sheet of paper if you prefer. Cards are organized as the following-

**Cards A-J:** Given a function, evaluate for a given value. (Example: Given a function, find f(2))

**Cards K-T:** Given a function, solve for x. (Example: Given f(x) = 20, find x). Students must be able to solve a two-step equation.

**Cards U-V:** Given a graph of a function, find the f(x) value that corresponds to a given x-value.

**Cards W-X:** Given a graph of a function, find the x value that corresponds to a given f(x) value.

Once they are finished, I have my students staple their “triples” together and place in a zip-lock bag. The letters make this super easy to grade! I included an answer key to use to ensure the correct cards are matched.
