Question

x = independent variable.. y = dependent variable.

anonymous · Answer

as months increase.. so do the number of CD's.  thus the number of CD's is dependent on the number of months.

you aren't even here.... boo hoo

anonymous · Answer

Let m be the number of months from now (M is the independent variable).

Let c be the number of CDs you own (C is the dependent variable).

Then c = 26 + 2m because every month, you get 2 more, and at month 0 (at the beginning) you had 26 CDs.

The domain is the natural numbers (all the integers greater than or equal to 0) and the range is all the even numbers from 26 to infinity.
