Evaluating Functions in Function Notation: Sample Algebra 1 EOC Questions

Function notation is the language the rest of Algebra 1 is written in. Students evaluate f(3), read a value off a graph or table, and say what the output means when the function models a real situation such as cost, height, or population.

How the Algebra 1 EOC tests this benchmark

This benchmark is drawn twice on a practice form because it appears so often on the real test. Items are limited to one-variable functions with no piecewise definitions and no composition. The output interpretation half is where the points move: the number is easy, the sentence explaining what it means in context is not.

Skills students need

Evaluate a function for a given input
Read f(x) values from a graph or a table
Interpret an output in a real-world context
Solve f(x) = k for the matching input
