Exponential Curves

The graph of* f*(*x*) = 2* ^{x}* is below. The value of

The curve above is an example when the value of b is greater than 1. What happens to the curve as the value of *b* increases? The graph below shows how the curve changes as the value of *b* increases. Notice that the y-intercept remains the same, but the curve gets steeper from left to right.
