Graphically, a function is concave up if its graph is curved with the opening upward (Figure 1a). Similarly, a function is concave down if its graph opens downward (Figure 1b). Figure 1. This figure shows the concavity of a function at several points. Notice that a function can be concave up regardless of whether it is increasing or decreasing.First, I would find the vertexes. Then, the inflection point. The vertexes indicate where the slope of your function change, while the inflection points determine when a function changes from concave to convex (and vice-versa). In order to find the vertexes (also named "points of maximum and minimum"), we must equal the first derivative of the function to zero, while to find the inflection ...The fact that its derivative, \(f'\text{,}\) is decreasing makes \(f\) concave down on the interval. Figure \(\PageIndex{7}\). At left, a function that is concave up; at right, one that is concave down. We state these most recent observations formally as the definitions of the terms concave up and concave down.Analyze concavity. g ( x) = − 5 x 4 + 4 x 3 − 20 x − 20 . On which intervals is the graph of g concave up? Learn for free about math, art, computer programming, economics, physics, chemistry, biology, medicine, finance, history, and more. Khan Academy is a nonprofit with the mission of providing a free, world-class education for anyone ... When f''(x) is positive, f(x) is concave up When f''(x) is negative, f(x) is concave down When f''(x) is zero, that indicates a possible inflection point (use 2nd derivative test) Finally, since f''(x) is just the derivative of f'(x), when f'(x) increases, the slopes are increasing, so f''(x) is positive (and vice versa) Hope this helps! Find wher the function is concave up and where it's concave down - identify any inflection points This problem has been solved! You'll get a detailed solution from a subject matter expert that helps you learn core concepts.of a function can tell you whether the linear approximation will be an overestimate or an underestimate. 1.If f(x) is concave up in some interval around x= c, then L(x) underestimates in this interval. 2.If f(x) is concave down in some interval around x= c, then L(x) overestimates in this interval.About this unit. The first and the second derivative of a function give us all sorts of useful information about that function's behavior. The first derivative tells us where a function increases or decreases or has a maximum or minimum value; the second derivative tells us where a function is concave up or down and where it has inflection points.Suppose that \(f''(a)>0\). This means that near \(x=a\), \(f'\) is increasing. If \(f'(a)>0\), this means that \(f\) slopes up and is getting steeper; if \(f'(a) < 0\), this means …Find where the function is concave up or down and the inflection points and the asymptotes.

Post any question and get expert help ...Let's look at the sign of the second derivative to work out where the function is concave up and concave down: For \ (x. For x > −1 4 x > − 1 4, 24x + 6 > 0 24 x + 6 > 0, so the function is concave up. Note: The point where the concavity of the function changes is called a point of inflection. This happens at x = −14 x = − 1 4.Calculate the second derivative of ff. Find where ff is concave up, concave down, and has inflection points. f′′(x)=f″(x)= ...
