On what intervals is f concave up or down

Web20 de dez. de 2024 · The intervals where concave up/down are also indicated. If the concavity of f changes at a point ( c, f ( c)), then f ′ is changing from increasing to … WebIf the interval is positive then this tells us the interval is concave up. Similarly, if the interval is negative then this tells us the interval is concave down. So in our example, our function is concave up on the interval (−∞,1) and our function is concave down on the interval (1,∞). The next example he looks at is: f (x)= (x2−1)3
