To determine whether a function is concave up or concave down using the second derivative, you can follow these steps: Find the second derivative of the function. This involves taking the derivative of the first derivative of the function. The second derivative is often denoted as f''(x) or d²y/dx². Identify the critical points of the function.Step 1: Finding the second derivative.

In this section, we also see how the β¦ The graph is concave down when the second derivative is negative and concave up when the second derivative is positive. Concave up on since is positive. Concave down on since is negative. Concave up on since is positive. Step 9If the second derivative is zero, the function is not concave up or down at that point. So we check some nearby points to see whether the concavity changes there. ... to actually graph a function without using a graphing calculator. So let's say our function, let's say that f of x is equal to 3x to the fourth minus 4x to the third plus 2. And ...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 ...

The Function Calculator is a tool used to analyze functions.

The calculator will also plot the function's graph.The turning point at ( 0, 0) is known as a point of inflection. This is characterized by the concavity changing from concave down to concave up (as in function β) or concave up to concave down. Now that we have the definitions, let us look at how we would determine the nature of a critical point and therefore its concavity.a) Find the intervals on which the graph of \( f(x) = x^4 - 2x^3 + x \) is concave up, concave down and the point(s) of inflection if any. b) Use a graphing calculator to graph \( f \) and confirm your answers to part a).2.

When f'(x) is zero, it indicates a possible local max or min (use the first derivative test to find the critical points) 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)
Using the second derivative test, f(x) is concave up when x<-1/2 and concave down when x> -1/2. Concavity has to do with the second derivative of a function.
