Question

You are packing books into a box. The box can hold at most 10 books. The function y=5.2x represent the weight y (in pounds) of x books

Is 52 the range?
Is 45 the range?
Is 15 the domain?
Is the domain discrete or continuous?

Answer 1

The domain is the input. It is the number of books. You can have 0-10 books. These would be the domains.

The range is the outputs. The outputs can be from 0 to 52 pounds.

The domain is discrete. The domain is the number of books. We cannot have half or a book or 3/4 of a book. So this will be discrete. The number of books can only be whole numbers up to 10.

Explanation:

Answer 2

52 is range

Explanation:

Range is the 'y' values the function can have

from 0 to 10 books would give a range of 0 - 52

Domain is the x-values 0, 1,2,3,4,56,7,8,9,10

discrete, because you cannot have anything but the whole numbers listed for the values of 'x'
