When Graphing Piecewise Functions Endpoints are very important Open Closed Arrow heads Keep in mind what you are graphing

vs Vocabulary Piecewise function: Points of Discontinuity: Has at least 2 equations Each has a different part of the domain Points of Discontinuity: Point where there is a break in the graph vs

Evaluate When given a function, , evaluate for f(3), just means to substitute in for the variables of the function. So:
