Which of the following functions are discontinuous at a = 7 7 Select all that apply. O A. f(x) = cos x O B. f(x) = sin x O C. f(x) = tan x O D. f(x) = sec x O E. f(x) = csc x O F. f(x) = cot xWhich statement correctly describes the function? mm :2: O A. It is continuous. O B. It is discontinuous because there is a value for a for which fla) is not dened. 0 C. It is discontinuous because there is a value of a such that 1122f (I) at flit!) . O D. It is discontinuous because there is a value for a such that lim x) does not exist. 1}2 The function fis continuous. What is the value of q? [6x-4, if x # 1 f (x) = 9 , if x = 1 O A. 0 O B. 1 O C. 2 O D. 4
