If f(x) = cos x + sinx, what is f"" (x)? f""(x) = sinx - cos x of"" (x) = sin x + cos x f"" (x) = sin x + cos x f""(x) = sinx - cos x Which of the following is true? If f(x) is increasing and f '(x) is positive, then f '(x) is negative and f is concave up. If f(x) is increasing and f '(x) is negative, then f'(x) is positive and f is concave up. If f(x) is increasing and f "(x) is positive, then f '(x) is positive and f is concave up. If f(x) is increasing and f ''(x) is positive, then f '(x) is positive and f is concave down. Which of the following is true? If f '(x) is 0, and f "(x) is positive, then f (x) is decreasing and f is concave up. If f '(x) is 0, and f "(x) is positive, then f (x) is increasing and f is concave up. If f '(x) is 0, and f "(x) is positive, then f (x) is flat and f is concave down.
