The second derivative is positive (f00(x) > 0): When the second derivative is positive, the function f(x) is concave up. 2. The second derivative is negative (f00(x) < 0): When the second derivative is negative, the function f(x) is concave down. 3. The second derivative is zero (f00(x) = 0): When the second derivative is zero, it correspondsNow, the second derivate test only applies if the derivative is 0. This means, the second derivative test applies only for x=0. At that point, the second derivative is 0, meaning that the test is inconclusive. So you fall back onto your first derivative. It is positive before, and positive after x=0. Therefore, x=0 is an inflection point.Another drawback to the Second Derivative Test is that for some functions, the second derivative is difficult or tedious to find.
