WebNow that we know the intervals where f f f f is concave up or down, we can find its inflection points (i.e. where the concavity changes direction). f f f f is concave down before x = − 1 x=-1 x = − 1 x, equals, minus, 1 , concave up after it, and is defined at x = − 1 x=-1 x = − 1 x, equals, minus, 1 . WebTo find the interval of on which the function is concave down and concave up, first, we need to find the second derivative of the function using the power rule. Recall the rules … Web19 de set. de 2024 · e) Determine the intervals where f ( x) is concave up and concave down I know that f ″ ( x) < 0 curve is concave down, if f ″ ( x) > 0, then the curve is concave down. I also know that if f ″ ( x) = 0, then x is the point of inflection, where the concavity changes. So I thought I compute it: 0 = ( x 2 − 4 x + 2) e ( − x + 4) x 2 − 4 x + 2 … highest inflated country
