Graph the exponential function f(x)=2^x. To graph the function, plot the points on the graph with x-values -2, -1, 0, 1, and 2. Next draw the asymptote(s).

Answer 1

Plot those points to get the graph:

The asymptote is the line the graph never quite gets to. In this case its a horizontal asymptote that is right on top of the x axis.
