2,我们说函数是凸的(concave down),是指函数的切线位于函数的上方。从图形上看,函数的切线的斜率是减少的,也就是说 \(f'(x)\) 减少。由上一节我们知道,函数减少的判断条件是它的导数为负,所以函数是凸的条件是 \(f^{\prime\prime}(x)<0\)。

To find the critical points of a two variable function, find the partial derivatives of the function with respect to x and y. Then, set the partial derivatives equal to zero and solve the system of equations to find the critical points. Use the second partial derivative test in order to classify these points as maxima, minima or saddle points.

Example 1: Determine the concavity of f (x) = x 3 − 6 x 2 −12 x + 2 and identify any points of inflection of f (x). Because f (x) is a polynomial function, its domain is all real numbers.

The calculator will also plot the function's graph.Using the second derivative test, f(x) is concave up when x<-1/2 and concave down when x> -1/2. Concavity has to do with the second derivative of a function. A function is concave up for the intervals where d^2/dx^2f(x)>0. A function is concave down for the intervals where d^2/dx^2f(x)<0. First, let's solve for the second derivative of the …We always need to check on both sides of the inflection point to make sure we go from positive to negative or negative to positive. After this we can determine the intervals of concavity. Notice that at x = pi, the second derivative has value f''(pi) = -sinpi - cospi = 1, so we're concave up on the interval ((3pi)/4, (7pi)/4).Question 296583: find the largest open interval at which function is concave up or concave down and find the location of any points of inflection. f(x)= x^4+8x^3-30x^2+24x-3 Please help with steps Answer by stanbon(75887) (Show Source): You can put this solution on YOUR website!Determine where the cubic polynomial is concave up, concave down and find the inflection points.

Consider the function f (x)=4x3+4x2 +1. Find the largest open intervals on which the function is concave up or concave down. If there is more than one interval, enter your intervals from left to right as they appear on the real line. Enter INF for ∞ and-INF for −∞.

Concave down = slope of function decreasing = negative second derivative. Concave up = slope of function increasing = positive second derivative. The first problem you would do best to sketch out, starting at negative infinity and going to positive infinity. This would demonstrate that the local minima are -8 and 8 and the local maximum is at 0.

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. Remember that an easy way to determine concavity is to evaluate the second derivative. For example, consider the six examples from the previous section.

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. It's clear, hopefully, that the second derivative will only be zero at \(t = 0\). Using this we can see that the second derivative will be negative if \(t < 0\) and positive if \(t > 0\). So the parametric curve will be concave down for \(t < 0\) and concave up for \(t > 0\). Here is a sketch of the curve for completeness sake.ection point at x= 1, and is concave down on (1;1). 4.

Free math problem solver answers your algebra, geometry, trigonometry, calculus, and statistics homework questions with step-by-step explanations, just like a math tutor. If the second derivative is positive on a given interval, then the function will be concave up on the same interval. Likewise, if the second derivative is negative on a given interval, the function will be concave down on said interval. So, calculate the first derivative first - use the power rule. #d/dx(f(x)) = d/dx(2x^3 - 3x^2 - 36x-7)#Given a curve y=f(x), a point of inflection is a point at which the second derivative equals to zero, f''(x)=0, and across which the second derivative changes sign. This means that the curve changes concavity across a point of inflection; either from concave-up to concave-down or concave-down to concave-up.
