What is the range of f(x)=sin(x)? a. the set of all real numbers -2pi≤y≤2pi b. the set of all real numbers -1pi≤y≤1 c. the set of all real numbers 0≤y≤2pi d. the set of all real numbers

Answer D:  The set of all real numbers.

Step-by-step explanation:

The trig function f(x) = sin x is periodic; that is, the graph repeats itself every 2pi units along the horizontal axis, regardless of whether you're moving to the left or to the right.  Thus, the domain of this function is "all real numbers."
