6. Which of the following could be the graph of the function f(x) = 3sin (b(x -)) + 1 depending on the value of b? (Assume that b is a real, positive number. There is some flaw in 3 of these graphs where no matter the value of b, the graph would always be wrong.) The labeled points are on the respective graphs a. b. (11=/12, 4) (x6, 0) (x/6, 1) (20. -3) (5 /12, -2) C. d. (5 13, -2) (203, -2)
