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
