How to evaluate a piecewise function with a hole

The video tutorial explains how to graph the function 2X + 5, focusing on the Y intercept and slope. It introduces constraints where X cannot equal zero, creating a hole in the graph. The function is evaluated at various points, including a special case at X = 0, where the function value is set to -1. The tutorial emphasizes understanding graph behavior and function evaluation without complex algebra.
