Determine concave up or down
WebMath Advanced Math Inspect the graph of the function to determine whether it is concave up, concave down or neither, on the given interval. A cube function, m (x) = - 4x³, on (-∞,0) On the interval (-∞,0), the function m (x) = − 4x³ is 3 concave down. neither concave up or concave down. concave up. WebNov 18, 2024 · We can calculate the second derivative to determine the concavity of the function’s curve at any point. Calculate the second derivative. Substitute the value of x. If f “ (x) > 0, the graph is concave upward at that value of x. If f “ (x) = 0, the graph may have a point of inflection at that value of x.

WebExample 5.4.1 Describe the concavity of f ( x) = x 3 − x . First, we compute f ′ ( x) = 3 x 2 − 1 and f ″ ( x) = 6 x . Since f ″ ( 0) = 0, there is potentially an inflection point at zero. Since f ″ ( x) > 0 when x > 0 and f ″ ( x) < 0 when x < 0 the concavity does change from down to up at zero, and the curve is concave down for ... WebKey Concepts. Concavity describes the shape of the curve. If the average rates are increasing on an interval then the function is concave up and if the average rates are decreasing on an interval then the function is concave down on the interval. A function has an inflection point when it switches from concave down to concave up or visa versa.
