Final answer:
The correct answer is D) Calculate coefficients using regression. Regression analysis is used to find the equation of the least-squares regression line for a set of data points.
Step-by-step explanation:
Linear, Quadratic, and Exponential Functions
The correct answer to the question is D) Calculate coefficients using regression. Regression analysis is used to find the equation of the least-squares regression line for a set of data points. This line can be used to represent a linear, quadratic, or exponential relationship between variables.
When data is entered into a calculator or computer and a scatter plot is created, regression analysis can be used to find the best-fitting equation for the data points. The calculator's regression function calculates the coefficients of the equation, which can be used to predict values and analyze the relationship between the variables.
