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.
Enter the function. Use ZoomDec.
Use ZoomStd.
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 yvalues are quite small, and the window will need to reflect that.
Enter the function. Start with ZoomDec
and use TRACE, ,
to find values. Use these values
to set the window. Check negative
values. Set the window. Graph the function.
