When Sara was born, her parents invested $5,000 into an annuity with a consistent 5% annual rate

of return and never touched the account again. Sara is now in high school and wants to write a

function to model the amount of money in her annuity account over time to help her determine the

amount of money she will have in the account when she turns 18.

Is this an example of a linear or exponential function? How do you know?
