Question

A school is ordering pencils for its students. The principal estimates that each student will use 30 pencils in one school year. The function y = 30x describes the total number of pencils, y, that the principal should order for x students. Which set of terms best describes the function y = 30x in this scenario?

A. discrete and linear

B.discrete and non-linear

C.continuous and linear

D.continuous and non-linear

Answer 1

A

Answer 2

Always 30 pencils for each student. Therefore this is linear because the number of pencils per student never changes. You have a set number of students, so this is discrete. It would be continuous if the principal continuously enrolled students to no end.

Answer is A
