WebThe second derivative of a function may also be used to determine the general shape of its graph on selected intervals. A function is said to be concave upward on an interval if f″(x) > 0 at each point in the interval and concave downward on an interval if f″(x) < 0 at each point in the interval. If a function changes from concave upward to concave downward or vice … WebJun 10, 2024 · A linear is in the form f (x) = mx +b where m is the slope, x is the variable, and b is the y-intercept. (You knew that!) We can find the concavity of a function by finding its double derivative ( f ''(x)) and where it is equal to zero. Let's do it then! f (x) = mx + b. ⇒ f '(x) = m ⋅ 1 ⋅ x1−1 +0. ⇒ f '(x) = m ⋅ 1. ⇒ f '(x) = m.

WebOct 19, 2024 · Concave up is also referred to as convex; this is where the second derivative is positive. Concave down is where the second derivative is negative. Thus, an inflection point is where the graph switches from being concave up to concave down (or vice-versa, if you are only considering going from left to right). f(x) = (x^2 - 8)e^x WebKey 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.
