6. The logistic function P(t) = 500,000 models the decreasing size of the gray whale population, P. t years since 2000. A graph of the function P and the horizontal asymptote are shown below, but the scale is not provided. Using the function P and the graph to the right, determine the truth value of each of the statements. Write either TRUE or FALSE in the space to the right of each statement. (a) There were 25,000 gray whales in the year 2000. (b) The gray whale population is expected to approach 20,000. 1111 (c) The gray whale population is expected to eventually go extinct. (d) The function P is invertible (has an inverse function)
