13. Let f be a function that is continuous on the closed interval [4, 16]. Given that f (4) = 2 and f (16) = 8, which of the following statements is guaranteed by the Intermediate Value Theorem? 0 f (.73) is linear 0 H10) = O f (3:) = 5 has at least one solution in the open interval (4,16) 0 There is at least one maximum on the open interval (4, 16) O f (cc) is always increasing 11. The table below gives values of a continuous function f. On the interval [3, 0] , the trapezoidal approximation for the area under the function, found with 3 intervals of equal length, is 3.5. What is the value of k? 2m+c m
