the domain is going to be ur x values....the number of minutes
therefore, ur domain is : I know it is either A or C.....I am thinking C because it does not have to be a whole minute...it can be 1.5 minutes...so that would eliminate A. final answer    is gonna be C
I think it's 

C.all real numbers from 0 to 3145
