Consider the function f(x) = cotx. Which of the following are true? Select all that apply. O A. f(x) is an even function. O B. f(x) has an asymptote at x = 0. O C. f(x) has a zero at x = 0. O D. f(x) has a period of IT.Sandra wants to evaluate 2mt[QT'] . Her work is shown below. What did she do wrong? 0 A' Since cotangent is an odd function, 2cot[ 9%] .e 2mt[97\"]. O B\" Since cotangent has a period of IT, 2cm [9%].- 20mg] . O 0' Since cotangent evaluated at i is not 0, long}: 2(0). 2 O D. Since cotangent cannot be multiplied by a factor, 2(0).- [1. IHHH ' W\" 7 Use the graph to answer the question. Look at the graph of for) = sin 1. Is this function periodic? Why or why not? I A. Yes, it is periodic. The value of for) varies between 1 and 1 repeatedly. B. Yes, it is periodic. It is a transformation of sin x. C. No, it is not periodic. The function does not repeat on regular intervals. 0- No, it is not periodic. The function is a transformation of l. I f(x) = 6n sin (4x) 20 15 x 2 Use the graph to answer the question. What set describes the zeroes of the function f (x) = 67 sin(4x) shown in the graph?O A. { x x= kx) for every integer k O B. {x| x= 4kx) for every integer k O C. x X = 7 for every integer k O D. (x x= 6/] for every integer k
