## Algebra 2 (1st Edition)

$e$ is a number, so we will use the same process as in section 7.1. We first note the shape of the graph of $e^x$, which is on page 493. Thus, we start with this shape for our graph. If the function is in the form $e^x$, we are done. However, if it is in the form $ae^{rk-h}+k,$ we shift the graph h units right and k units up. (Note, $a$ and $r$ change the steepness of the graph.) The domain is all real numbers, and the range is all values greater than 0.
