Graphs of Exponential Functions

In this video, we are going to look at graphs of exponential functions.
For example:
The graph of
y=2^x
grows steeper in a positive direction as x values increase after plotting points as shown in the video.
The graph of
y=-(2)^x
grows steeper in a negative direction as x values increase after plotting points, and is a reflection over the x-axis of the first graph.
The graph of
y=(\frac{1}{2})^x
grows steeper at a slower rate as x values increase after plotting points, and is a reflection over the y-axis of y=2^x
