To answer the this item, simply multiply the given functions,
                             (f·g)(x) = f(x)  x g(x)
Plugging in the expression,
                           (f·g)(x) = (4x + 6)(2x²)
                                       = 8x³ + 12x²
Thus, the answer to this item is letter A. 8x^3 + 12x^2.
