On what intervals is f concave up or down
WebA function f f is concave up (or upwards) where the derivative f' f ′ is increasing. This is equivalent to the derivative of f' f ′, which is f'' f ′′, being positive. Similarly, f f is concave down (or downwards) where the derivative f' f ′ is decreasing (or equivalently, f'' f ′′ is … f f f f is concave up ∪ \cup ∪ \cup We can see that the graph of f f f f changes … Learn for free about math, art, computer programming, economics, physics, … The Algebra 2 course, often taught in the 11th grade, covers Polynomials; … Learn how to code computer programs, how to design algorithms that make … Learn high school geometry for free—transformations, congruence, … Web18 de nov. de 2024 · We can calculate the second derivative to determine the concavity of the function’s curve at any point. Calculate the second derivative. Substitute the value of x. If f “ (x) > 0, the graph is concave upward at that value of x. If f “ (x) = 0, the graph may have a point of inflection at that value of x.

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 … 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
