Find where its graph is concave up and concave down. Find the relative extrema and inflection points and sketch the graph of the function. f (x)=x^5-5x Concavity Practice Problem 2.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.If you get a negative number then it means that at that interval the function is concave down and if it's positive its concave up. If done so correctly you should get that: f(x) is concave up from (-oo,0)uu(3,oo) and that f(x) is concave down from (0,3) You should also note that the points f(0) and f(3) are inflection points.

Solution: Since f′(x) = 3x2 − 6x = 3x(x − 2) , our two critical points for f are at x = 0 and x = 2 . We used these critical numbers to find intervals of increase/decrease as well as local extrema on previous slides. Meanwhile, f″ (x) = 6x − 6 , so the only subcritical number is at x = 1 . It's easy to see that f″ is negative for x ...

Concavity. The concavity of the graph of a function refers to the curvature of the graph over an interval; this curvature is described as being concave up or concave down. Generally, a concave up curve has a shape resembling "∪" and a concave down curve has a shape resembling "∩" as shown in the figure below. Concave up. Explanation: 1) If f ″ ( a) = 0, then ( a, f ( a)) is a inflection point. Consider the function f (x)=4x3+4x2 +1. Find the largest open intervals on which the function is concave up or concave down. If there is more than one interval, enter your intervals from left to right as they appear on the real line. Enter INF for ∞ and-INF for −∞.To determine concavity, analyze the sign of f''(x). f(x) = xe^-x f'(x) = (1)e^-x + x[e^-x(-1)] = e^-x-xe^-x = -e^-x(x-1) So, f''(x) = [-e^-x(-1)] (x-1)+ (-e^-x)(1) = e^-x (x-1)-e^-x = e^-x(x-2) Now, f''(x) = e^-x(x-2) is continuous on its domain, (-oo, oo), so the only way it can change sign is by passing through zero.

The opposite is convex meaning "curved or rounded outward.". Both words have been around for centuries but are often mixed up. Advice in mirror may be closer than it appears.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^7you have to calculate f''(x) first. f'(x)=7x^6 f''(x)=42x^5 Now we have to check where f''(x ...The concavity of a curve tells us whether the tangent lines lie above or below the curve.

If the second derivative is positive at a point, the graph is bending upwards at that point. Similarly, if the second derivative is negative, the graph is concave down. This is of particular interest at a critical point where the tangent line is flat and concavity tells us if we have a relative minimum or maximum. 🔗.
