The graph of a function f is concave up when f ′ is increasing. That means as one looks at a concave up graph from left to right, the slopes of the tangent lines will be increasing.

Notice how the tangent line on the left is steep, downward, corresponding to a small value of f ′.Answer : The first derivative of the given function is 3x² - 12x + 12. The second derivative of the given function is 6x - 12 which is negative up to x=2 and positive after that. So concave downward up to x = 2 and concave upward from x = 2. Point of inflexion of the given function is at x = 2.Free polynomial equation calculator - Solve polynomials equations step-by-stepWorking of a Concavity Calculator. The concavity calculator works on the basis of the second derivative test. The key steps are as follows: The user enters the function and the specific x-value. The calculator evaluates the second derivative of the function at this x-value. If the second derivative is positive, the function is concave up. An inflection point is a point on the curve where concavity changes from concave up to concave down or vice versa. Let's illustrate the above with an example.
