Final answer:
To graph a quadratic function with a vertex calculator, enter the data into a calculator, make a scatter plot, and use the regression function to find the equation of the least-squares regression line.
Step-by-step explanation:
Graph of a Quadratic Function with Vertex Calculator
- Enter the data into a calculator and make a scatter plot.
- Use the calculator's regression function to find the equation of the least-squares regression line. Add this to your scatter plot from Part A.
The graph of a quadratic function can be obtained by plotting the data points and finding the equation of the quadratic function using regression analysis.
