In 9 46, write each expression in the standard form a + bi.

7.1 Exponential Functions and Their Graphs Copyright © Cengage Learning. All rights reserved. Exponential Functions The base a = 1 is excluded because it yields f(x) = 1 = 1. This is a constant function, not an exponential function. 2 Example 1 – Graphs of y = a x x In the same coordinate plane, sketch the graph of f(x) = 2 and g(x) = 4 . Solution: Complete the table below for each function, and Figure 7.1 shows the graphs of the two functions. Figure 7.1 3 Graphing y = a x
