Answer
The range is all numbers greater than -2, and the domain is all real numbers.
Work Step by Step
We first note the shape of the graph of $b^x$ (where b is a fraction), which is on page 486. 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.)
