#### Answer

The domain is all real numbers and the range is all values greater than -2.

#### Work Step by Step

We first note the shape of the graph of $b^x$, which is on page 478. Thus, we start with this shape for our graph.
If the function is in the form $b^x$, we are done. However, if it is in the form $ab^{x-h}+k,$ we shift the graph h units right and k units up. (Note, $a$ changes the steepness of the graph.)
