Final answer:
The appropriate calculator tool for graphing a piecewise non-linear function is the Piecewise Graphing Calculator. The TI-83, TI-83+, and TI-84+ calculators also support such graphing functions by allowing multiple expressions to be entered for different intervals.
Step-by-step explanation:
When graphing a piecewise non-linear function, the suitable option among the ones provided would be A) Piecewise Graphing Calculator. This tool is specifically designed to graph functions that have different expressions for different intervals of the independent variable.
For users of the TI-83, TI-83+, or TI-84+ calculators, which are very common in high school mathematics, creating a scatter plot and conducting regression analysis can be done following these steps:
- Enter the data into the calculator to make a scatter plot.
- Use the calculator's regression function to find the equation of the best-fit line.
- Add the regression line to your scatter plot to visualize the relationship between the data points.
For piecewise functions, you may need to use the calculator's Y= equation editor to enter multiple function expressions for the different intervals of the function and then analyze the graph accordingly.
