Select the correct answer. Which function is an odd function?
OA. f(x)= cos( – 21 x)
O B. f(x) = csc(-320
f(1) = sec (573)
OD. f(x) = cos(4x)
OC. f(t) = sec

The graph of the function f(x) = (x + 2)(x + 6) is shown below. which statement about the function is true? the function is positive for all real values of x where x > –4. the function is negative for all real values of x where –6 < x < –2. the function is positive for all real values of x where x < –6 or x > –3. the function is negative for all real values of x where x < –2.
