Question

A teacher notices a correlation between students’ scores on homework assignments and their scores on corresponding quizzes. The line of best fit for the data is given by the formula q=1.2h−25 , where h is the student homework score and q is the student quiz score. Which of the following relates the domain of this function to this scenario? (Assume that the homework does not have extra credit).

[−25,25]

[0,1.2]

[0,100]

[50,90]

Answer 1

[0,100]

Since homework scores can vary from 0 to 100, the domain of the function should also include all possible homework scores between 0 and 100.
