Function concave up and down calculator.
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. We find it convenient to pick a standard terminology and run with it - and in this case concave up and concave down were chosen to describe the direction of the concavity/convexity.

The small space is outside of the trapezoid, but ...You'll get a detailed solution from a subject matter expert that helps you learn core concepts. Question: Step 1 of 2: Determine the intervals on which the function is concave upward and concave downward. Step 2 of 2: Determine the x-coordinates of any inflection point (s) in the graph.

To find the domain of a function, consider any restrictions on the input values that would make the function undefined, including dividing by zero, taking the square root of a negative number, or taking the logarithm of a negative number. Remove these values from the set of all possible input values to find the domain of the function.(W) Consider the function f (x) = a x 3 + b x where a > 0. (a) Consider b > 0. (i) Find the x-intercepts.(ii) Find the intervals on which f is increasing and decreasing. (iii) Identify any local extrema. (iv) Find the intervals on which f is concave up and concave down. (b) Consider b < 0. (i) Find the x-intercepts.(ii) Find the intervals on which f is increasing and decreasing.Key Concepts. Concavity describes the shape of the curve. If the average rates are increasing on an interval then the function is concave up and if the average rates are decreasing on an interval then the function is concave down on the interval. A function has an inflection point when it switches from concave down to concave up or visa versa.
The inflection point is a point where the graph of the function changes from concave up to concave down or vice versa. To calculate these points you have to find places where #f''(x)=0# and check if the second derivative changes sign at this point. For example to find the points of inflection for #f(x)=x^7# you have to calculate #f''(x)# first.
Just because it's concave-up to the left & right of 0 doesn't mean it's concave up at 0. Unlike y=x^2 and despite appearances on a graphing calc, y=x^4 is truly "flat" (neither conc-up nor -down) at 0. f''(x)=0 for all x for a line, which is not a failure but is the correct answer: flat at all points.Concave down on (0, √3) since f′′ (x) is negative.

A function, g g is concave if −g − g is a convex function. A function is non-concave if the function is not a concave function. Notice that a function can be both convex and concave at the same time, a straight line is both convex and concave. A non-convex function need not be a concave function. For example, the function f(x) = x(x − 1 ...

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 ...Here's the best way to solve it. 1.
