Unformatted text preview: . We will see some of the applications of this function in the final section of this chapter. Let’s get a quick graph of this function. Example 2 Sketch the graph of f ( x ) = e x . Solution Let’s first build up a table of values for this function. x -2 -1 0 1 2 f(x) 0.1353… 0.3679… 1 2.718… 7.389… To get these evaluation (with the exception of x = 0 ) you will need to use a calculator. In fact, that is part of the point of this example. Make sure that you can run your calculator and verify these numbers. Here is a sketch of this graph. © 2007 Paul Dawkins 282 College Algebra Notice that this is an increasing graph as we should expect since e = 2.718281827 K > 1 . There is one final example that we need to work before moving onto the next section. This example is more about the evaluation process for exponential functions than the graphing process. We need to be very careful with the evaluation of exponential functions. Example 3 Sketch the graph of...
