Since the line of best fit is represented by h=1.5s-20, and we are assuming no extra credit is offered on homework or quizzes, the domain values for this function would be any possible homework score s that Gemma could achieve.
Since homework scores typically fall within a range from 0 to 100, the domain values would be represented in interval notation as [0, 100].
Gemma’s parents noticed a correlation between her scores on homework assignments and her scores on corresponding quizzes. The line of best fit for the data is given by the formula h=1.5s-20, where s is Gemma’s homework score and h is her quiz score. How would you represent the domain values of this function assuming that no extra credit is offered on homework or quizzes? Write your answer in interval notation.
