This year the number of students who participated in sports was 317. Each year the number of students who participate in sports increased by 4%,

Which function can be used to model the number of students participating in sports after x years?

• f(x) = 317(4)^x

• f(x) = 4x + 317

• f(x) = 317(1.04)^x

• f(x) = 1.04x + 317
