Write an exponential function to model the situation. You invest $1500. Your investment increases at a rate of 3.5%.

• B(t) = 1500(0.965)^t

• B(t) = 1500(1.035)^t

• B(t) = 1500(.035)^t

• B(t) = 1500(1.965)^t

Determine the y-intercept and asymptote for the following exponential function.

Hint: for the asymptote , just click which dot it would be, BE CAREFUL on this one!
