Evaluating Function Outputs from Graphs

Miacademy & MiaPrep Learning Channel

This educational video provides a clear, step-by-step tutorial on how to evaluate functions using their graphical representations. The narrator transitions students from algebraic substitution (plugging numbers into equations) to visual interpretation (reading coordinates on a graph). The video explains that the x-axis represents input values and the y-axis represents function output values, demonstrating how to locate points on a coordinate plane to solve for specific function values.
