Given any two functions f and g, which of the following statements is always true? A) If x is in the domain of f, then x must be in the domain of f−g.
B) If x is in the domain of f+g, then x must be in the domain of f and x must be in the domain of g.
C) If x1 is in the domain of f and x2 is in the domain of g, then the product, x1x2, must be in the domain of fg.
D) If x is not in the domain of f/g, then x is not in the domain of g.
