Generally, 5 ≤ k ≤ 15.Free derivative calculator - high order differentiation solver step-by-stepA critical point is when the derivative equals 0. And while it is always negative where you indicated, the derivative itself is increasing at one point. A much easier example to see this is -x^2. if this were the derivative of something, this also has a critical point at (0,0).

Plug in a value that lies in each interval to the second derivative; if f '' (x) is positive, the function is concave upwards for that interval, and if f '' (x) is negative, the function is concave downwards for that interval. As a note, any point at which the function changes concavity is called a point of inflection. Some textbooks and ...A graph is concave up where its second derivative is positive and concave down where its second derivative is negative. Thus, the concavity changes where the second derivative is zero or undefined. Such a point is called a point of inflection. The procedure for finding a point of inflection is similar to the one for finding local extreme values ...

Check the second derivative test to know the concavity of the function at that point. What is a critical point in a function? A critical point of a function is a point where the derivative of the function is either zero or undefined.Question: 0 (b) Calculate the second derivative of f.

You can think of potential inflection points as critical points for the first derivative — i.e. they may occur if f"(x) = 0 OR if f"(x) is undefined. An example of the latter situation is f(x) = x^(1/3) at x=0. (Note: f'(x) is also undefined.)

To determine concavity, analyze the sign of f''(x). f(x) = xe^-x f'(x) = (1)e^-x + x[e^-x(-1)] = e^-x-xe^-x = -e^-x(x-1) So, f''(x) = [-e^-x(-1)] (x-1)+ (-e^-x)(1) = e^-x (x-1)-e^-x = e^-x(x-2) Now, f''(x) = e^-x(x-2) is continuous on its domain, (-oo, oo), so the only way it can change sign is by passing through zero. (The only partition numbers are the zeros of f''(x)) f''(x) = 0 if and only ...Explore math with our beautiful, free online graphing calculator.
