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. 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.

Ascientist wants to use a model to present the results of his detailed scientific investigation. why would a model be useful? a )because the model makes the concepts easier to understand b) because the model is easy to put together and to use c) because the model prevents other scientists from asking questions d) because the model requires the audience to pay full attention to it i don't know what to choose because between a and d a is much more likely than d because it only wants to get the attention of the audience. i'm confuse.
