Given a scatterplot, you will tell what type of function the data models. There are many models possible but we will concentrate on linear, quadratic, exponential, and logarithmic.
First, you need to review what these four graphs look like. Follow the link below to review the shapes of these graphs. There are more graphs than the four you need in this lesson, but it won't hurt to see others.
Pay close attention to slides 2, 4, 9, and 10. Click on a graph (or use the swipe motion for mobile devices) to move through the slides. Make drawings of each graph for reference later.
