Victor will start paying off his credit card in January. He uses the function f(x) = -35 + 2,500 to model the amount of money he owes x months after January. How much money does he owe at the beginning of January?

To find out how much money Victor owes at the beginning of January (which is x = 0 months after January), we can substitute x = 0 into the function f(x).

f(0) = -35 + 2,500
f(0) = 2,500 - 35
f(0) = 2,465

Therefore, Victor owes $2,465 at the beginning of January.
