b would Pelt A 5. (5 points) An ecological engineer wants to model the population change of an invasive species of fish in a certain lake using the Method of Selected Points. She has a set of data (ti, N(), where to is the length of time (in years) since the fish first entered the lake and N, is the number of fish present in the lake at that time. She then plots these points on semilogarithmic paper, draws her empirical best fit line, and identifies two points on this line from the graph: Point 1 = (5 years, 150) and Point 2 = (9 years, 200). Determine the resulting mathematical model; that is, find the function f(t) such that N = f(t) best models the data according to the Method of Selected Points. a, x 1 . K
