(x)=a", show that f(A+B) = f(A) f(B). Rewrite f(A+B) by substituting A+B for x in the given function. f(A+B)=a A+B Which law of exponents can be used to rewrite the expression above as a product? S ** O A. a S a OC. as a=a+t O E. a = 1 Rewrite the expression f(A + B) as a product to show that f(A+B) = f(A) f(B). f(A+B)= Since each factor in the product above can be written as f(A) and f(B), f(A+B) = f(A) f(B).
