The size of the beaver population at a national park increases at the rate of 4.3% per year. If the size of the current population is 142, find how many beaver there should be in 4 years. Use the function f(x)=4e^0.043t and round to the nearest whole number

1. just replace t with 4 and evaluate, using your calculator
population = 4 e^(.043(4))
= ....

I think your function should have been
f(t) = 142 e^(.043t)
