Figure 3.4.5: A number line determining the concavity of f in Example 3.4.1. The number line in Figure 3.4.5 illustrates the process of determining concavity; Figure 3.4.6 shows a graph of f and f ″, confirming our results. Notice how f is concave down precisely when f ″ (x) < 0 and concave up when f ″ (x) > 0.f (x) = x³ is increasing on (-∞,∞). A function f (x) increases on an interval I if f (b) ≥ f (a) for all b > a, where a,b in I. If f (b) > f (a) for all b>a, the function is said to be strictly increasing. x³ is not strictly increasing, but it does meet the criteria for an increasing function throughout it's domain = ℝ.Use the first derivative test to find the location of all local extrema for f(x) = x3 − 3x2 − 9x − 1. Use a graphing utility to confirm your results. Solution. Step 1. The derivative is f ′ (x) = 3x2 − 6x − 9. To find the critical points, we need to find where f ′ (x) = 0.An inflection point is defined as a point on the curve in which the concavity changes. (i.e) sign of the curvature changes. We know that if f ” > 0, then the function is concave up and if f ” < 0, then the function is concave down. If the function changes from positive to negative, or from negative to positive, at a specific point x = c ...This is my code and I want to find the change points of my sign curve, that is all and I want to put points on the graph where it is concave up and concave down. (2 different shapes for concave up and down would be preferred. I just have a simple sine curve with 3 periods and here is the code below. I have found the first and second derivatives.

We know that the sign of the derivative tells us whether a function is increasing or decreasing; for example, when f′ (x)>0, f (x) is increasing.Informal Definition. Geometrically, a function is concave up when the tangents to the curve are below the graph of the function. Using Calculus to determine concavity, a function is concave up when its second derivative is positive and concave down when the second derivative is negative.

The Function Calculator is a tool used to analyze functions. It can find the following for a function: parity, domain, range, intercepts, critical points, intervals of increase/decrease, local and global extrema, concavity intervals, inflection points, derivative, integral, asymptotes, and limit. The calculator will also plot the function's graph.

For example, consider the function $$$ f(x)=x^3 $$$. To find its inflection points, we follow the following steps: Find the first derivative: $$ f^{\prime}(x)=3x^2 $$ Find the second derivative: $$ f^{\prime\prime}(x)=6x $$

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.Ex 5.4.19 Identify the intervals on which the graph of the function $\ds f(x) = x^4-4x^3 +10$ is of one of these four shapes: concave up and increasing; concave up and decreasing; concave down and increasing; concave down and decreasing.

To determine concavity, analyze the sign of f''(x). f(x) = xe^-x f'(x) = (1)e^-x + x[e^-x(-1)] = e^-x-xe^-x = -e^-x(x-1) So, f''(x) = [-e^-x(-1)] (x-1)+ (-e^-x)(1) = e^-x (x-1)-e^-x = e^-x(x-2) Now, f''(x) = e^-x(x-2) is continuous on its domain, (-oo, oo), so the only way it can change sign is by passing through zero. (The only partition numbers are the zeros of f''(x)) f''(x) = 0 if and only ...A Concave function is also called a Concave downward graph. Intuitively, the Concavity of the function means the direction in which the function opens, concavity describes the state or the quality of a Concave function. For example, if the function opens upwards it is called concave up and if it opens downwards it is called concave down.In other words, at the inflection point, the curve changes its concavity from being concave up to concave down, or vice versa. For example, consider the function $$$ f(x)=x^3 $$$. To find its inflection points, we follow the following steps: Find the first derivative: $$ f^{\prime}(x)=3x^2 $$ Find the second derivative: $$ f^{\prime\prime}(x)=6x $$Plug an x-value from each interval into the second derivative: f(-2) < 0, so the first interval is concave down, while f(0) > 0, so the second interval is concave up. This agrees with the graph.Question: 0 (b) Calculate the second derivative of f.

f is concave up on I if f'(x) is increasing on I , and f is concave down on I if f'(x) is decreasing on I . Concavity Theorem Let f be twice differentiable on an open interval, I. If f"(x) > 0 for all x on the interval, then f is concave up on the interval. If f"(x) < 0 for all x on the interval, then f is concave down on the interval.Question: I have tried to find the concave up and concave down intervals and I don't understand why my answers are wrong! Please help and explain why!The graph of a function f is concave up when f ′ is increasing. That means as one looks at a concave up graph from left to right, the slopes of the tangent lines will be increasing. Consider Figure 3.4.1 (a), where a concave up graph is shown along with some tangent lines. Notice how the tangent line on the left is steep, downward, corresponding to a small value of f ′.So, for example, let f ( x) = x 4 − 4 x 3 and follow the steps to see where the function is concave up or concave down: Step 1: Find the second derivative. f ′ ( x) = 4 x 3 − 12 x 2. f ...Equations Inequalities Scientific Calculator Scientific Notation Arithmetics Complex Numbers Polar/Cartesian Simultaneous Equations System of Inequalities Polynomials Rationales Functions Arithmetic & Comp.
