How many times does x 3 change concavity
WebSolution: We find where f00(x) = 0: first, f0(x) = 3x236x 10, so f00(x) = 6x 36. Setting f00(x) = 0, we have 6x 36 = 0, so x = 6. Therefore, we look for an inflection point here. Since f00(x) is negative for x < 6 and positive for x > 6, the concavity of f(x) does change here, so f(x) does have an inflection point.
