SP #3 Unit I Concept 1:Graphing Exponential Functions

The viewer needs to pay close attention to solving or the x-intercept. We cannot take the log of a negative number, so if this occurs, it is undefined, meaning no x-intercept. Additionally, it is important to notice that the range depends on the asymptote. If you look at the graph, you can see that the graph never goes below 1 and goes up to infinity, giving us the range of (1, infinity). Also when choosing key points, the 3rd key point should be h.
