If mc005-1.jpg and d(x) = x + 3, what is the domain of (cd)(x)?

all real values of x all real values of x except x = 2 all real values of x except x = –3 all real values of x except x = 2 and x = –3

all real values of x all real values of x except x = 2 all real values of x except x = –3 all real values of x except x = 2 and x = –3
