#### Explanation:

The Domain for almost any exponential function is

For the Range, find the asymptote to help.

The asymptote is

The asymptote means a line that the exponential function will always get closer to, but will never touch (graphing calculators will round it off eventually though).

Since the function is decreasing from infinity, the range is

Here is a graph:

graph{2*(1/2)^(2x)+3 [-10, 10, -5, 5]}
