# concave up and down calculator wolfram

(i) We will say that the graph of f(x) is concave up on I iff f '(x) is increasing on I. Collection of teaching and learning tools built by Wolfram education experts: dynamic textbook, lesson plans, widgets, interactive Demonstrations, and more. Note: Geometrically speaking, a function is concave up if its graph lies above its tangent lines. Of particular interest are points at which the concavity changes from up to down or down to up; such points are called inflection points . If it's positive, it is concave up, if it's negative it is concave down. And I wanna think about the intervals over which g is either concave upwards or concave downwards. Compute answers using Wolfram's breakthrough technology & knowledgebase, relied on by millions of students & professionals. Online Integral Calculator » Solve integrals with Wolfram|Alpha. Now let's just remind ourselves what these things look like. Note that the value a is directly related to the second derivative, since f ''(x) = 2a.. Unlimited random practice problems and answers with built-in Step-by-step solutions. (i) We will say that the graph of f(x) is concave up on I iff f '(x) is increasing on I. I am given the following two functions, and I am to figure out if they are concave. a) Find the intervals on which the graph of f(x) = x + x is concave up, concave down and the point(s) of inflection if any. Curve segment that lies above its tangent lines is concave upward. Wolfram Demonstrations Project » Explore thousands of free applications across science, mathematics, engineering, technology, business, art, finance, social sciences, and more. If my calculations are correct, this function is convex in certain cases and concave in certain different cases. In other words, the graph of f is concave up. We say that a graph is concave up if the line between two points is above the graph, or alternatively if the first derivative is increasing. Thus f is concave up from negative infinity to the inflection point at (1, –1), and then concave down from there to infinity. It can calculate and graph the roots (x-intercepts), signs, Local Maxima and Minima, Increasing and Decreasing Intervals, Points of Inflection and Concave Up/Down intervals. I'm looking for a concave down increasing-function, see the image in the right lower corner. if, for any points and in , the function So: f (x) is concave downward up to x = −2/15. Show Instructions. As always, you should check your result on your graphing calculator. The graph is concave down on the interval because is negative. In general, you can skip parentheses, but be very careful: e^3x is e^3x, and e^(3x) is e^(3x). p. 1132, 2000. Let f(x) be a differentiable function on an interval I. b) Use a graphing calculator to graph f and confirm your answers to part a). Limits Go to Limits Ch 7. Wolfram Demonstrations Project » Explore thousands of free applications across science, mathematics, engineering, technology, business, art, finance, social sciences, and more. https://mathworld.wolfram.com/ConcaveFunction.html. That kind of information is useful when it comes to analyzing graphs using derivatives. Points of discontinuity show up here a bit more than in the First Derivative Test. If we are trying to understand the shape of the graph of a function, knowing where it is concave up and concave down helps us to get a more accurate picture.
