1. Suppose you pour water into a cylinder of such cross section, ConcaveUp trickles water down the trough and holds water in the tub. ConcaveDown trickles water away and spills out, water falling down. In the first case slope is <0 to start with, increases to 0 and next becomes > 0. In the second case slope is >0 at start, decreases to 0 and ...The second derivative is f'' (x) = 30x + 4 (using Power Rule) And 30x + 4 is negative up to x = −4/30 = −2/15, and positive from there onwards. So: f (x) is concave downward up to x = −2/15. f (x) is concave upward from x = −2/15 on. Note: The point where it changes is called an inflection point.Explanation: To find when a function is concave, you must first take the 2nd derivative, then set it equal to 0, and then find between which zero values the function is negative. …For a quadratic function f (x)=ax^2+bx+c, if a>0, then f is concave upward everywhere, if a<0, then f is concave downward everywhere. Wataru · 6 · Sep 21 2014.Hence the function f f f is concave-up for x > 1 x>1 x > 1 and concave-down for x < 1 x<1 x < 1. x = 1 x=1 x = 1 is point of inflection of the function f f f.

We have seen previously that the sign of the derivative provides us with information about where a function (and its graph) is increasing, decreasing or stationary. We now look at the "direction of bending" of a graph, i.e. whether the graph is "concave up" or "concave down".

When asked to find the interval on which the following curve is concave upward $$ y = \int_0^x \frac{1}{94+t+t^2} \ dt $$ What is basically being asked to be done here?

Calculus I: Finding Intervals of Concavity ...Working 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.When a function is concave up, the second derivative will be positive and when it is concave down the second derivative will be negative. Inflection points are where a graph switches concavity from up to down or from down to up. Inflection points can only occur if the second derivative is equal to zero at that point. About Andymath.comExplanation: To find when a function is concave, you must first take the 2nd derivative, then set it equal to 0, and then find between which zero values the function is negative. …Jul 12, 2022 · Estimate from the graph shown the intervals on which the function is concave down and concave up.
