In order to understand how to solve this problem, the viewer needs to pay special attention to the four parts of the exponential graph equation and how they affect the graph. Another thing to take note of is the fact that exponential graphs have an asymptote of y=k, which means that there are no restrictions on the domain (-inf. , + inf.). The viewer should also pay attention to how the range of the graph is written: from the lowest point to the highest point. Another thing to be aware of is the use of the 2nd TABLE function when obtaining the y-values of the key points.
