Bonnie buys a used car for $2500. She calculates her average monthly expenses for gas, insurance, and maintenance at $150 per month. The function f(x) = 150x + 2500 represents her total cost of owning the car for x number of months. What is the domain for this situation?

r u sure its because i googled it in here and some say its B C D so i dont know which one is the right answer

anonymous · Answer

what letter would it be A B C or D?

anonymous · Answer

just use your sense to analyse it 
suppose if you put x=5 it means you own car for 5 months
monthly expense=5*150
total car cost=2500
f(x) is the total expense which gives out the same value as calculated from the above procedure

and there is no variable y whose value determines the expression

i think its A?
