Finding concave up and down. Graphically, a function is concave up if its graph is curved with the opening upward (Figure 1a). Similarly, a function is concave down if its graph opens downward (Figure 1b). Figure 1. This figure shows the concavity of a function at several points. Notice that a function can be concave up regardless of whether it is increasing or decreasing.

The concavity changes at points b and g. At points a and h, the graph is concave up on both sides, so the concavity does not change. At points c and f, the graph is concave down on both sides. At point e, even though the graph looks strange there, the graph is concave down on both sides – the concavity does not change.

Example 1: Determine the concavity of f (x) = x 3 − 6 x 2 −12 x + 2 and identify any points of inflection of f (x). Because f (x) is a polynomial function, its domain is all real numbers. Testing the intervals to the left and right of x = 2 for f″ (x) = 6 x −12, you find that. hence, f is concave downward on (−∞,2) and concave ...

7 years ago. Concavity and convexity are opposite sides of the same coin. So if a segment of a function can be described as concave up, it could also be described as convex down.Inflection points are points where the function changes concavity, i.e. from being "concave up" to being "concave down" or vice versa. They can be found by considering where the second derivative changes signs. In similar to critical points in the first derivative, inflection points will occur when the second derivative is either zero or undefined.Green = concave up, red = concave down, blue bar = inflection point. 1. f x = x x − 1 2 x + 5. 2. Adjust h or change zoom level if the blue bar does not show up. 3 ...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 lower the exponent on all the variables by one and multiply by the original variable.The second derivative tells us if a function is concave up or concave down. If f'' (x) is positive on an interval, the graph of y=f (x) is concave up on that interval. We can say that f is increasing (or decreasing) at an increasing rate. If f'' (x) is negative on an interval, the graph of y=f (x) is concave down on that interval.Use a number line to test the sign of the second derivative at various intervals. A positive f ” ( x) indicates the function is concave up; the graph lies above any drawn tangent lines, and the slope of these lines increases with successive increments. A negative f ” ( x) tells me the function is concave down; in this case, the curve lies ...1.

Using the results from the previous section, we are now able to determine whether a critical point of a function actually corresponds to a local extreme value. In this section, we also see how the …Subject classifications. A function f (x) is said to be concave on an interval [a,b] if, for any points x_1 and x_2 in [a,b], the function -f (x) is convex on that interval (Gradshteyn and Ryzhik 2000). If f′′(x)<0, the graph is concave down (or just concave) at that value of x. If f′′(x)=0 and the concavity of the graph changes (from up to down or vice versa), then the graph is at an inflection point . The sum of two concave functions is itself concave and so is the pointwise minimum of two concave functions, i.e. the set of concave functions on a given domain form a semifield. Near a strict local maximum in the interior of the domain of a function, the function must be concave; as a partial converse, if the derivative of a strictly concave ...

When is a function concave up? When the second derivative of a function is positive then the function is considered concave up. And the function is concave down on any interval where the second derivative is negative. How do we determine the intervals? First, find the second derivative. Then solve for any points where the second derivative is 0.
