Which statement is true? If f(x) is decreasing, and f "(x) is positive, then f '(x) is positive and f is concave down. O If f(x) is decreasing, and f "(x) is positive, then f '(x) is negative and f is concave up. O If f(x) is decreasing, and f "'(x) is positive, then f '(x) is positive and f is concave down. O If f(x) is decreasing, and f "(x) is positive, then f '(x) is positive and f is concave up.
