4. (2 points. Circle the letter of the correct answer.) Consider the function f(x) = x. Which one of the statements below is true? a. The instantaneous rate of change of f(x) at x = 1 equals 1, the instantaneous rate of change at x = 3 equals 9, and the average rate of change of f(x) between x = 1 and x = 3 equals 4. b. The instantaneous rate of change of f(x) at x = 1 equals 1, the instantaneous rate of change at x = 3 equals 9, and the average rate of change of f(x) between x = 1 and x = 3 equals 6. c. The instantaneous rate of change of f(x) at x = 1 equals 1, the instantaneous rate of change at x = 3 equals 9, and the average rate of change of f(x) between x = 1 and x = 3 equals 8. d. The instantaneous rate of change of f(x) at x = 1 equals 2, the instantaneous rate of change at x = 3 equals 6, and the average rate of change of f(x) between x = 1 and x = 3 equals 4. e. The instantaneous rate of change of f(x) at x = 1 equals 2, the instantaneous rate of change at x = 3 equals 6, and the average rate of change of f(x) between x = 1 and x = 3 equals 6. f. The instantaneous rate of change of f(x) at x = 1 equals 2, the instantaneous rate of change at x = 3 equals 6, and the average rate of change of f(x) between x = 1 and x = 3 equals 8.
