Piecewise functions: how to graph, evaluate, and write them

You can try colino for free here: https://colino.app/get/youtube In colino, you take photos of your math homework and get interactive videos. You can ask questions while you watch. We graph a piecewise function one rule at a time, using open and closed circles at the endpoints. Then we find function values and write a piecewise function from a graph. There's also a problem you can try yourself. 0:00 How to Graph Piecewise Functions 1:23 Evaluating Piecewise Functions 2:33 Write a Piecewise Function from a Graph 3:40 Practice Problem and Summary 4:56 Try colino For Algebra 2, grades 10 and 11. #math #algebra #piecewisefunctions
