AP Precalculus Section 1.13 Example: TI-84+ to Find the Minimum Value (Calculator)

Random AP Precalculus Problems (I found on the Internet). These are not official AP Collegeboard examples, but they will definitely get the job done!

To find the minimum value of a function using a TI-84+ calculator, follow these steps:

1. Enter the function: Press the "Y=" key and enter the function you want to find the minimum value for.

2. Set the window: Go to the "WINDOW" menu (usually located under the "WINDOW" or "FORMAT" button) and set the appropriate range for the x-values and y-values. Ensure that the x-range covers the interval where you expect the minimum to be.

3. Plot the function: Press the "GRAPH" button to plot the function on the calculator screen.

4. Trace the graph: Press the "TRACE" button.

5. Move the cursor to the left or right using the arrow keys until you are near the minimum point on the graph.

6. Once near the minimum, press the "2ND" button followed by the "CALC" (or "TRACE") button.

7. Choose "Minimum" from the menu that appears.

8. The calculator will prompt you to specify a left bound, right bound, and guess. Follow the prompts and select points that enclose the minimum. The calculator will then calculate and display the minimum value.

9. Read the minimum value from the calculator's screen. It will provide both the x-coordinate and the corresponding y-coordinate, which is the minimum value of the function.

That's how you can use a TI-84+ calculator to find the minimum value of a function.
