Usually our task is to find where a curve is concave upward or concave downward:. Definition. A line drawn between any two points on the curve won't cross over the curve:. Let's make a formula for that! First, the line: take any two different values a and b (in the interval we are looking at):. Then "slide" between a and b using a value t (which is from 0 to 1):1. taking the second derivative I got x = 16 3 x = 16 3 as the critical point. I assume that you mean that you set fβ²β²(x) = 0 f β³ ( x) = 0 and found a solution of x = 16 3 x = 16 3. This is not a critical point. Rather it is an inflection point. In other words, this is where the function changes from concave up to concave down (or vice ...The intervals of convexity (concavity) of a function can easily be found by using the following theorem: If the second derivative of the function is positive on certain interval, then the graph of the function is concave up on this interval. If it's negative - concave down. I.e.:Jun 15, 2014 at 13:40. 2. It depends on your definition of concave: there are the notion of "concave" and "strictly concave". In x β₯ 0 x β₯ 0 arctan(x) arctan. β‘. ( x) is concave, but not strictly concave. (The difference between the two notions translate in terms of the second derivative as the two conditions fβ²β² β€ 0 f β³ β€ 0 or ...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.
Intuitively, the Concavity of the function means the direction in which the function opens, concavity describes the state or the quality of a Concave function. For example, if the function opens upwards it is called concave up and if it opens downwards it is called concave down. The figure below shows two functions which are concave β¦

Solution: Since fβ²(x) = 3x2 β 6x = 3x(x β 2) , our two critical points for f are at x = 0 and x = 2 . We used these critical numbers to find intervals of increase/decrease as well as local extrema on previous slides. Meanwhile, fβ³ (x) = 6x β 6 , so the only subcritical number is at x = 1 . It's easy to see that fβ³ is negative for x ...
If you get a negative number then it means that at that interval the function is concave down and if it's positive its concave up. If done so correctly you should get that: f(x) is concave up from (-oo,0)uu(3,oo) and that f(x) is concave down from (0,3) You should also note that the points f(0) and f(3) are inflection points.
