here is the graph

graph{2^-x [-10, 10, -5, 5]}

#### Explanation:

Start by changing

Here are some characteristics of

-it will have y-intercept (0,1)

-the domain is all reals

-has

-is a decreasing function

-the horizontal asymptote is

To graph, start with the point (0,1) and multiply

then graph accordingly making sure to get close to zero, but never actually reach it.
