OBJECTIVE: SWBAT USE DOMAIN/RANGE OF A FUNCTION AND PLOT THEM ON A GRAPH  

Today in class we learned how to plot a graph. We learned the words intercept, origin, and slope. The intercept is where the line or graph “intercepts” the axis. The origin is the starting point, not the center. To make a line you need three points; when reading the line you read it from left to right. The slope is always a fraction and you need to draw arrows at the end of the lines you draw. The reason is because the line is continuous and never ends. There are two steps to plotting a graph. Step one: locate the intercept and step two: use slope. An example is show below.
