Which statement is true?
OA. )
The function f(x) = cos(x) is an odd function because f(-) = f(x).
B. The function f(x) = sin(x) is an odd function because f(-x) = -f(x).
OC. The function (1) sin(x) is an even function because its graph is symmetric about the origin.
D. The function f(x) = cos(x) is an even function because its graph is symmetric about the origin.
