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? (2 points)
A) discrete and linear
B) discrete and non-linear
C) continuous and linear
D) continuous and non-linear

anonymous · Answer

it's linear 100% and probably discrete but i'm not sure

anonymous · Answer

A) discrete and linear

myininaya · Answer

i think it is discrete since the amount of students can only be represented by an integer

anonymous · Answer

but we don't know amount of students it can even be infinity or no? :D

I agree with myininaya,
it can only take on integer values, you can't order half a pencil.
On the other hand it is plotted linearly...

myininaya · Answer

you can not have 3.5 or the sqrt(3) students
