Take x^2. It's concave up everywhere, but it is also decreasing until it gets to x=0. In fact if you use the f function from the video it is decreasing until it gets to x=5. f in the video is concave up everywhere, so just being concave up doesn't guarantee that its integral will also be concave up. I hope that helps.We first established that the graph of a function is concave up if the function is increasing at an increasing rate. Consequently, the function is concave down if the is increasing at a decreasing rate. Since here the coefficient x x x is greater than 0 0 0 and the exponent is less than 1 1 1, it means that the function is concave down.This video defines concavity using the simple idea of cave up and cave down, and then moves towards the definition using tangents.
