WebJul 7, 2024 · 1 Answer. If a function is undefined at some value of x , there can be no inflection point. However, concavity can change as we pass, left to right across an x values for which the function is undefined. f (x)=1x is concave down for x<0 and concave up for x>0 . The concavity changes “at” x=0 . WebAug 26, 2024 · The concavity is the value of the 2nd derivative or twice differentiable function at point x = 3.25, and the function is concave up when that value is positive, and concave down when the value is negative.

WebIf our function is concave up, the trapezoids we get from the trapezoid rule cover too much area, so we get an overestimate. If our function is concave down, the trapezoids don't cover enough area, so we get an underestimate. If our function has no concavity (is a straight line), the trapezoid sum is just right.

This is somewhat lower than our approximation. Note that the function 1−e−t is concave down, so the value of the derivative is decreasing, meaning the derivative at the beginning of an interval is always larger than at the end. For this reason, our Euler’s method approximation continues to overestimate the actual solution.
