Walkthrough of Part A. To determine whether f (x) f (x) is concave up or down, we need to find the intervals where f'' (x) f ′′(x) is positive (concave up) or negative (concave down). Let’s first find the first derivative and second derivative using the power rule. f' (x)=3x^2-6x+2 f ′(x) =3x2 −6x+2.

The first derivative is f'(x)=3x^2-6x and the second derivative is f''(x)=6x-6=6(x-1). The second derivative is negative when x<1, positive when x>1, and zero when x=1 (and of course changes sign as x increases "through" x=1). That means the graph of f is concave down when x<1, concave up when x>1, and has an inflection point at x=1.Expert Answer.

Inflection points are points where the function changes concavity, i.e. from being "concave up" to being "concave down" or vice versa. They can be found by considering where the second derivative changes signs. In similar to critical points in the first derivative, inflection points will occur when the second derivative is either zero or ...Second Derivative and Concavity. Graphically, a function is concave up if its graph is curved with the opening upward (Figure \(\PageIndex{1a}\)).

When we have determined these points, we divide the domain of \(f\) into smaller intervals and determine the sign of \(f''\) over each of these smaller intervals. If \(f ...

Step 2: Take the derivative of f ′ ( x) to get f ″ ( x). Step 3: Find the x values where f ″ ( x) = 0 or where f ″ ( x) is undefined. We will refer to these x values as our provisional inflection points ( c ). Step 4: Verify that the function f ( x) exists at each c value found in Step 3.Solution: Since f′(x) = 3x2 − 6x = 3x(x − 2) , our two critical points for f are at x = 0 and x = 2 . We used these critical numbers to find intervals of increase/decrease as well as local extrema on previous slides. Meanwhile, f″ (x) = 6x − 6 , so the only subcritical number is at x = 1 . It's easy to see that f″ is negative for x ...Free secondorder derivative calculator - second order differentiation solver step-by-step If f ′′(x) < 0 f ′ ′ ( x) < 0 for all x ∈ I x ∈ I, then f f is concave down over I I. We conclude that we can determine the concavity of a function f f by looking at the second derivative of f f. In addition, we observe that a function f f can switch concavity (Figure 6). If f '' > 0 on an interval, then f is concave up on that interval. If f '' 0 on an interval, then f is concave down on that interval. If f '' changes sign (from positive to negative, or from negative to positive) at some point x = c, then there is an Inflection Point located at x = c on the graph. The above image shows an Inflection Point.

For f ( x) = –2 x3 + 6 x2 – 10 x + 5, f is concave up from negative infinity to the inflection point at (1, –1), then concave down from there to infinity. To solve this problem, start by finding the second derivative. Now set it equal to 0 and solve. Check for x values where the second derivative is undefined.If a function is bent upwards, it’s referred to as concave up. Conversely, if it bends downward, it’s concave down. The point of inflection is where this change in bending direction takes place. Understanding the concavity function is pivotal, especially when we’re on the lookout for inflection points.
