This video shows how to find the formula of a piecewise function when given a graph. The first step is to write a definition for the graph, which is done by identifying the different domains shown in the graph. The second step is writing formulas for each domain specified by the lines in the graph. The pointslope formula is used to identify the slope and yintercept for the leftmost domain, which has a sloped line. A point and horizontal line make for simpler equations in the other pieces of the function. This video clearly demonstrates how to compose a formula of a piecewise function from its graph.
