B. Examples
4. Exponential Functions
When you enter functions that involve exponents, it is important that you put parentheses around the exponent.
i) Example: Graph the function shown. ZoomDec does not give a good graph, but a look at the table indicates that ZoomStd will be a good window to use.
|
Enter the function.   |
Use ZoomDec.  
|
Go to TABLE.
|
Use ZoomStd.
 |

ii) Example: Graph the function shown. You can see that ZoomDec does not show very much of the graph, but ZoomStd gives a good view. Notice that the domain of the function is x>2.
iii) Example: Graph the function shown. Instead of using the TABLE to find a window, we will use TRACE to determine a proper viewing window. You can see that the y-values are quite small, and the window will need to reflect that.
and use TRACE,,
