# How do you find limits on a graphing calculator?

I am not sure if there is a TI-84 Plus function that directly finds the value of a limit; however, there is a way to approximate it by using a table. Let us approximate the value of the limit

Step 1: Go to "Y=", then type in the function.

Step 2: Go to "TBL SET" (2nd+WINDOW), then set TblStart=.97 and

(Note: TblStart is the starting x-value in the table, so put a number slightly smaller that the number x approaches.

Step 3: Go to "" TABLE (2nd+GRAPH).

As you can see in the table above, the function value (

To find limits on a graphing calculator, follow these steps:

- Enter the function into the calculator.
- Press the "Graph" button to plot the function on the graph.
- Use the arrow keys to navigate to the point on the graph where you want to find the limit.
- Press the "Trace" or "Calc" button (depending on your calculator model).
- Select the "Limit" option from the menu.
- Enter the desired x-value or approach direction for the limit.
- The calculator will calculate and display the limit value.

Note: Make sure to check the calculator's manual or guide for specific instructions based on your calculator model.

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
