Chapter 11.2, Problem 27E

In Problems 23–30, the graph of an exponential function is given. Match each graph to one of the following functions. It may prove useful to create a table of values for each function to help you identify the correct graph. See Objective 2.

1. a. f(x) = 2^x
2. b. f(x) = 2^−x
3. c. f(x) = 2^{x + 1}
4. d. f(x) = 2^{x − 1}
5. e. f(x) = −2^x
6. f. f(x) = 2^x + 1
7. g. f(x) = 2^x − 1
8. h. f(x) = −2^−x
