71. The period B Set the constants A = 3, C = D = 0. a. Plot f(r) for the values B = 1, 3, 27, 57 over the interval -47 SIs 47. Describe what happens to the graph of the general sine function as the period increases. b. What happens to the graph for negative values of B? Try it with B = -3 and B = -27. 72. The horizontal shift C Setthe constants A = 3, B = 6, D = 0. a. Plot f(x) for the values C = 0, 1, and 2 over the interval -47 SIS 47. Describe what happens to the graph of the general sine function as C increases through positive values. b. What happens to the graph for negative values of C? c. What smallest positive value should be assigned to C so the graph exhibits no horizontal shift? Confirm your answer with a plot. 73. The vertical shift D Set the constants A = 3, B = 6, C = 0. a. Plot f(x) for the values D = 0, 1, and 3 over the interval -47 SxS 47. Describe what happens to the graph of the general sine function as D increases through positive values. b. What happens to the graph for negative values of D? 74. The amplitude A Set the constants B = 6, C = D = 0. a. Describe what happens to the graph of the general sine func- tion as A increases through positive values. Confirm your answer by plotting fx) for the values A = 1, 5, and 9. b. What happens to the graph for negative values of A?
