. If A is the set of values of x at which F(x)=0, and B is the set of values of x at which g(x)=0, what can you say about the set of values of x at which f(x)g(x)=0?

(A) It is the intersection of A and B.
(B) It is the union of A and B.
(C) It is a proper subset of the union of A and B.
(D) It is the Cartesian product of A and B.

• b) because when either f(x) or g(x) is 0 total value of the expression ll be zero
  so it is the union of A and B
