This document contains 28 multiple choice questions about functions and their graphs. The questions cover topics such as slope, linear and quadratic functions, intercepts, domains and ranges. Sample questions ask about the slope of a given line, the opening direction of a parabola, and the x and y-intercepts of an equation. The answers to the questions are provided at the end.
