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 square root function, n (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 ...

WebSep 21, 2014 · Jan 22, 2016. For a quadratic function ax2 +bx + c, we can determine the concavity by finding the second derivative. f (x) = ax2 + bx +c. f '(x) = 2ax +b. f ''(x) = 2a. In any function, if the second derivative is positive, the function is concave up. If the second derivative is negative, the function is concave down. WebThe concavity of the graph of a function refers to the curvature of the graph over an interval; this curvature is described as being concave up or concave down. Generally, a concave up curve has a shape resembling "∪" and a concave down curve has a shape resembling "∩" as shown in the figure below. Concave up.
