Function concave up and down calculator.

The nature of the concavity can be identified from the elements of the matrix. The Hessian matrix can be written as follows: If the determinant of the Hessian matrix is greater than zero at (xo, yo) and. If fxx (xo, yo) > 0, the function f is concave up at (xo, yo). If fxx (xo, yo) < 0, the function f is concave down at (xo, yo).Increasing, concave. Correct answer: Decreasing, convex. Explanation: First, let's find out if the graph is increasing or decreasing. For that, we need the first derivative. To find the first derivative, we can use the power rule.

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. The concavity of the function changes from concave up to concave down at 𝑥 = − 2 3. This is a point of inflection but not a critical point. We will now look at an example of how to calculate the intervals over which a polynomial function is concave up or concave down.
