Graph g(x) = (1/2)^x - 1 an Exponential Function with Fractional Base

Step 1: Choose any values for x. Choose some negative values, zero, and some positive values.
Step 2: Evaluate to find the corresponding y-values.
Step 3: Plot the points. The points you plot the better the graph will look.

ip: All exponential functions of the form y = b^(x+h) + k have a horizontal asymptote at y = k.
