Finding concave up and down

An inflection point exists at a given x -value only if there is a tangent line to the function at that number. This is the case wherever the first derivative exists or where there’s a vertical tangent. Plug these three x- values into f to obtain the function values of the three inflection points. The square root of two equals about 1.4, so ...

Subject classifications. A function f (x) is said to be concave on an interval [a,b] if, for any points x_1 and x_2 in [a,b], the function -f (x) is convex on that interval (Gradshteyn and Ryzhik 2000).Intervals Where Function is Concave Up and Concave Down Polynomial ExampleIf you enjoyed this video please consider liking, sharing, and subscribing.Udemy Co...May 22, 2015 · Answer link. First find the derivative: f' (x)=3x^2+6x+5. Next find the second derivative: f'' (x)=6x+6=6 (x+1). The second derivative changes sign from negative to positive as x increases through the value x=1. Therefore the graph of f is concave down when x<1, concave up when x>1, and has an inflection point when x=1. Dec 21, 2020 · The second derivative is evaluated at each critical point. When the graph is concave up, the critical point represents a local minimum; when the graph is concave down, the critical point represents a local maximum. Concavity and convexity are opposite sides of the same coin. So if a segment of a function can be described as concave up, it could also be described as convex down.
