The graph is attached.

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.) The domain is all real numbers, and the range is all real numbers greater than -1.
