WebThe second derivative is f’’ (x) = 2, again by the power rule. Since 2 is always positive, we have f’’ (x) > 0 for all values of x. This means that f (x) is convex (concave up) for all values of x, and it opens upward. (using the S e c o nd Derivative Test) You … Web10 If the domain of f is connected, then the derivative of f being everywhere zero means f is constant. You can define a function on ( 0, 1) ( 2, 3) which is constant on each component ( 0, 1) and ( 2, 3), but not constant overall. – Thomas Andrews Nov 11, 2015 at 20:45 Add a comment 2 Answers Sorted by: 9

If the derivative of a function is zero, is the function a constant

WebThe derivative of a function may be used to determine whether the function is increasing or decreasing on any intervals in its domain. If f′ (x) > 0 at each point in an interval I, then the function is said to be increasing on I. f′ (x) … WebSo when the video is asking for an interval where the derivative is greater than 0, you must look for a slope that is increasing or getting more and more steep in a sense.
