How do you graph absolute value equations on graphing calculator
(TI83+)?
To graph absolute value equations on a TI83+ calculator, follow these steps:
1. Press the "y=" button on your calculator.
2. Enter the equation you want to graph, including the absolute value bars.
3. Press the "graph" button.
4. Your graph will appear on the screen.
Yes, you can graph multiple absolute value equations on the same graph. Simply enter each equation into the "y=" editor and press the "graph" button. Each equation will appear in a different color on the graph.
To find the vertex of an absolute value equation on a TI83+ calculator, follow these steps:
1. Press the "2nd" button, then the "trace" button to access the "CALC" menu.
2. Scroll down to option 4: "Maximum" or "Minimum" (depending on whether the vertex is a maximum or minimum point).
3. Press enter twice to select the option.
4. Use the arrow keys to move the cursor to the left and right of the vertex, then press enter to find the coordinates of the vertex.
To change the window settings on a TI83+ calculator, follow these steps:
1. Press the "window" button.
2. Use the arrow keys to adjust the values for "Xmin," "Xmax," "Ymin," and "Ymax." These values represent the minimum and maximum values for the x and y axes.
3. Press enter to save your changes and view the updated graph.
Yes, you can use your TI83+ calculator to find the x-intercepts of an absolute value equation. Follow these steps:
1. Press the "2nd" button, then the "trace" button to access the "CALC" menu.
2. Scroll down to option 2: "Zero" and press enter.
3. Use the arrow keys to move the cursor to the left and right of the x-intercept, then press enter to find the x-coordinate.
4. Repeat this process to find the other x-intercept, if applicable.
