The first and the second derivative of a function can be used to obtain a lot of information about the behavior of that function. For example, the first derivative tells us where a function increases or decreases and where it has maximum or minimum points; the second derivative tells us where a function is concave up or down and where it has inflection points.Similarly, a function is concave down if its graph opens downward (Figure \(\PageIndex{1b}\)). Figure \(\PageIndex{1}\) This figure shows the concavity of a function at several points. Notice that a function can be concave up regardless of whether it is increasing or decreasing.A function (in black) is convex if and only if the region above its graph (in green) is a convex set.

We know that the sign of the derivative tells us whether a function is increasing or decreasing; for example, when f′ (x)>0, f (x) is increasing.

Maximum preserves convexity and minimum preserves concavity. So the maximum of two concave functions may be neither concave nor convex. It may become double peaked. For example, f(x) = max[−|x + 1|, −|x − 1|] f ( x) = max [ − | x + 1 |, − | x − 1 |] has an "M"-shaped graph. The minimum of two concave functions is always concave.42. A function f: R → R is convex (or "concave up") provided that for all x, y ∈ R and t ∈ [0, 1] , f(tx + (1 − t)y) ≤ tf(x) + (1 − t)f(y). Equivalently, a line segment between two points on the graph lies above the graph, the region above the graph is convex, etc. I want to know why the word "convex" goes with the inequality in ...Determine the intervals on which the given function is concave up or down and find the point of inflection.

The first derivative is parabola that has positive coefficient a. Parabolas with positive coefficient a ("happy" parabolas or concave) are negative between zeros and positive everywhere else. So our function is increasing when x<-2 and x>2. In order to determine where the function is concave up or down, we have to find the second derivative.Wolfram Language function: Compute the regions on which an expression is concave up or down.

Oct 30, 2023 · Hence, what makes \(f\) concave down on the interval is the fact that its derivative, \(f'\), is decreasing. Figure 1.31: At left, a function that is concave up; at right, one that is concave down. We state these most recent observations formally as the definitions of the terms concave up and concave down. 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. We find it convenient to pick a standard terminology and run with it - and in this case concave up and concave down were chosen to describe the direction of the concavity/convexity.

The second derivative tells whether the curve is concave up or concave down at that point. If the second derivative is positive at a point, the graph is bending upwards at that point. Similarly, if the second derivative is negative, the graph is concave down.

Find step-by-step Calculus solutions and your answer to the following textbook question: Determine the intervals where the graph of the given function is concave up and concave down, and identify inflection points. f (x)=sin x-cos x.To find the critical points of a two variable function, find the partial derivatives of the function with respect to x and y. Then, set the partial derivatives equal to zero and solve the system of equations to find the critical points. Use the second partial derivative test in order to classify these points as maxima, minima or saddle points.Suppose that \(f''(a)>0\). This means that near \(x=a\), \(f'\) is increasing. If \(f'(a)>0\), this means that \(f\) slopes up and is getting steeper; if \(f'(a) < 0\), this means …f (x) = x4 − 8x2 + 8 f ( x) = x 4 - 8 x 2 + 8.

Inflection points are found in a way similar to how we find extremum points. However, instead of looking for points where the derivative changes its sign, we are looking for points where the second derivative changes its sign.

And since f is decreasing on the interval [ 5, 13] , we know g is concave down on that interval. g changes concavity at x = 5 , so it has an inflection point there. Problem 1. This is the graph of f . Let g ( x) = ∫ 0 x f ( t) d t .A concave function can be non-differentiable at some points. At such a point, its graph will have a corner, with different limits of the derivative from the left and right: A concave function can be discontinuous only at an endpoint of the interval of definition.With the increasing reliance on technology in our daily lives, having a reliable calculator at our fingertips has become more important than ever. While there are numerous calculat...Recall that d/dx(tan^-1(x)) = 1/(1 + x^2) Thus f'(x) = 1/(1 + x^2) Concavity is determined by the second derivative. f''(x) = (0(1 + x^2) - 2x)/(1 + x^2)^2 f''(x) =- (2x)/(1 + x^2)^2 This will have possible inflection points when f''(x) = 0. 0 = 2x 0= x As you can see the sign of the second derivative changes at x= 0 so the intervals of concavity are as follows: f''(x) < 0--concave down: (0 ... When f''(x) is positive, f(x) is concave up When f''(x) is negative, f(x) is concave down When f''(x) is zero, that indicates a possible inflection point (use 2nd derivative test) Finally, since f''(x) is just the derivative of f'(x), when f'(x) increases, the slopes are increasing, so f''(x) is positive (and vice versa) Hope this helps!
