複選題2. A function f on R is odd if f(-x)"=-f(x) for all xR while it is even if f(-x) = f(x) for all x R. Suppose that g and h are two functions on R. (a) If g is an even function, then the composite function h o g must be even. (b) If g is an odd function and , then the limit must be -3.(c) If g is an even function and , then the limit must be 3.Among the above three statements, how many of them are true? (A)Only one.(B) Only two. (C)All of them. (D) None of them.
