Question

Charles uses a graphing calculator to find a quadratic regression model f for a given set of data. When he compares model f to an earlier regression model g for the same data, he determines that g more accurately models the data. Which of the following statements are true? Select all that apply.

A. Function f likely had fewer residuals near the x-axis than function g.
B. Function f likely had more residuals equal to 0 than function g.
C. Function g had more residuals near the y-axis than function f.

Answer 1

C

Explanation:

a is wrong because residuals are solved using y and not x

b is wrong because a residual closer to 0 would be more accurate, but f is less accurate than g

c is right because residuals are solved using y and a more accurate residual would be closer to the real answer's y value

hope this helped ^_^
