WebLet's see if we can use the derivatives to tell us that it is concave up: The first derivative is 2 x, which is always increasing. So the first derivative tells us the graph is concave up. The second derivative is 2, which is positive! So the second derivative test tells us that the graph is concave up. Both tests give us the correct answer! WebNov 18, 2024 · If the function is concave up, its derivative f' (x) is increasing. If the function is concave down, its derivative f' (x) is decreasing. When the function f (x) has an inflection point at point x = a. f' (x) either goes from increasing to decreasing or vice-versa. That means the graph of the function f' (x) has a minimum/maximum at x = a.

WebThis derivative is increasing in value, which means that the second derivative over an interval where we are concave upwards must be greater than 0. If the second derivative is greater than 0, that means … WebMath Calculus The graph of the derivative f' (x) of a function is given below. Justify your answers to the following questions. (a) Find all critical numbers (x-coordinates) of f (z) (b) Where is the function y = f (x) decreasing? (c) Where is the function y = f (x) concave up? WebSep 7, 2024 · To determine concavity, we need to find the second derivative f ″ (x). The first derivative is f ′ (x) = 3x2 − 12x + 9, so the second derivative is f ″ (x) = 6x − 12. If the function changes concavity, it occurs either when f ″ (x) = 0 or f ″ (x) is undefined. Since f ″ is defined for all real numbers x, we need only find where f ″ (x) = 0. dhhs healthy opportunities
