I'm not sure how to do these type of questions. Help?!

Samantha puts an initial $500 into a savings account. The account has a 4% annual compound interest rate. What is the function that best represents Samantha's account and how much does she have in savings after 5 years? Round your answer to the nearest dollar.
Hint: Use the formula, f(x) = P(1 + r)x.

f(x) = 500(1.4)x, $2,689
f(x) = 500(0.04)x, $512
f(x) = 500(1.04)x, $608
f(x) = 500(1.04)x, $527
