Iris has been studying an invasive population of snails. This particular snail has no local predators, so the population grows wildly. She has observed that the population follows an exponential rate of growth for fifteen years.

1.Create your own exponential function, f(x), which models the snail population. You will need to identify the principal population of the snails and the rate of growth each year. Explain to Iris how your function shows the principal population and the rate of growth, in complete sentences.

Would it have to be
f(x)=15(.3)^x
or
f(x)=200(1+.3)^15x

I know we can make our own, but I'm not sure if 15 would be the y-intercept or not.
