    辛普森求积公式,以下正确的是
    A: $\int_a^b {f(x)} dx \approx {{b - a} \over 6}[f(a) + 4f({{a + b} \over 2}) + f(b)]$
    B: $\int_a^b {f(x)} dx \approx {{b - a} \over 6}[f(a) + 4f({{a + b} \over 2}) - f(b)]$
    C: $\int_a^b {f(x)} dx \approx {{b - a} \over 6}[f(a) - 4f({{a + b} \over 2}) + f(b)]$
    D: $\int_a^b {f(x)} dx \approx {{b + a} \over 6}[f(a) + 4f({{a - b} \over 2}) + f(b)]$
