Which of the functions graphed in Exercises 1–6 are one-to-one, and which are not?
America is getting older. The graph shows the projected elderly U.S. population for ages 65–84 and for ages 85 and older.The formula E = 5.8√x + 56.4 models the projected number of elderly Americans ages 65–84, E, in millions, x years after 2020.a. Use the formula to find the projected increase in the number of Americans ages 65–84, in millions, from 2030 to 2060. Express this difference in simplified radicalform.b. Use a calculator and write your answer in part (a) to the nearest tenth. Does this rounded decimal overestimate or underestimate the difference in the projected data shown by the bar graph ? By how much?
Each of Exercises 81–84 shows the graphs of the first and second
derivatives of a function y = f(x). Copy the picture and add to it a
sketch of the approximate graph of f, given that the graph passes
through the point P.
