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

Question

, 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).(1 point)
Responses

[−25,25]
left bracket negative 25 comma 25 right bracket

[50,90]
left bracket 50 comma 90 right bracket

[0,100]
left bracket 0 comma 100 right bracket

[0,1.2]

Answer 1

In this scenario, the function \( q = 1.2h - 25 \) relates the homework scores \( h \) (which range from 0 to 100) to the quiz scores \( q \). Since homework scores typically fall between 0 and 100, the domain of the function (the possible values for \( h \)) should also reflect this range.

Thus, the most appropriate option for the domain in this context, considering typical scores for homework assignments, is:

[0, 100] (left bracket 0 comma 100 right bracket)
