Lesson 1

Read “Example 2” on pages 341 and 342 of your textbook to find out how the characteristics of a graph can be determined from the exponential equation.

Exponential equations can be used to represent data from a real-life context. In Self-Check 2 you will look at the characteristics of an exponential graph that relates to the context from Try This 1.

Self-Check 2

1. In Try This 1 you examined the relationship between the number of folds in a piece of paper, f, and how many layers of paper are created, L. The equation that describes the relationship is L = 2f. This can be rewritten as y = 2x. Use this equation to determine the y-intercept and x-intercept and whether the graph is increasing or decreasing. Explain how you determined your answers. Answer
