How do you find the relative maximum and minimum of a graph using a graphing calculator? Specifically, a Texas Instruments 82, if possible? Thanks!
Plot the graph. Look at the graph, look the points of maxim (slope=0) and the min (slope=0).

Thank you!
To find the relative maximum and minimum of a graph using a Texas Instruments 82 graphing calculator, you can follow these steps:
1. Enter the function into the calculator. Press the "Y=" button, and enter the equation or function you want to graph.
2. Adjust the window. Press the "WINDOW" button and set appropriate values for the x and y ranges to ensure the relevant portion of the graph is displayed.
3. Graph the function. Press the "GRAPH" button to plot the graph of the function.
4. Identify the maximum and minimum points. Look at the graph on your calculator screen and identify any points where the slope is zero, as these could be potential maximum or minimum points. You can do this by observing where the graph crosses the x-axis or changes direction.
5. Zoom in if necessary. If the maximum or minimum points are not clear, you can use the zoom feature on your calculator to get a closer look. Press the "ZOOM" button and select an option such as "Zoom Box" or "Zoom In" to focus on a specific region of the graph.
6. Determine the coordinates. Once you have identified the potential maximum and minimum points, use the arrow keys on your calculator to move the cursor to those points. The coordinates of the cursor will be displayed on the screen.
By following these steps, you can find the relative maximum and minimum points of a graph using a Texas Instruments 82 calculator. Additionally, you can refer to online resources like the link you provided (http://www.richland.edu/james/ti82/minmax/) for visual demonstrations and further guidance.
