Question 2

Given a set of data points that appear to follow a curved pattern opening upwards, which function type is most likely appropriate to fit the data?

Question 3

You have fit a linear model to a dataset and calculated the residuals. Which of the following characteristics of the residual plot would indicate that the linear model is a good fit?

Question 4

A dataset shows exponential growth. Which of the following is the general form of the exponential model that can be used to fit the data?
