解析 f is an odd function, so f(-x)=-f(x). g is an even function, so g(-x)=g(x). Then (f⚬g)(-x)=f(g(-x))=f(g(x))=(f⚬g)(x). So f⚬g is even. Also, (g⚬f)(-x)=g(f(-x))=g(-f(x))=g(f(x))=(g⚬f)(x), so g⚬f is even.反...

奇函数(odd function),定义为,任意f(x)=-f(-x)的函数,即为奇函数。 偶函数(even function),定义为,任意f(x)=f(-x)的函数,即为偶函数。 奇函数和偶函数在y轴上有一定的对称性。 发布于 2021-06-06 18:20 函数 赞同3添加评论 分享喜欢收藏申请转载 ...
The sum of two even functions is even The sum of two odd functions is odd The sum of an even and odd function is neither even nor odd (unless one function is zero).Multiplying:The product of two even functions is an even function. The product of two odd functions is an even function...
奇函数定义为对于任意的x，满足f(x) = -f(-x)。这意味着在函数图像上，对于任何点(x, y)，其关于原点对称的点(-x, -y)也一定在图像上。奇函数的图像通常关于y轴旋转180度后与自身重合。偶函数则定义为对于任意的x，满足f(x) = f(-x)。这意味着对于任何点(x, y)，其关于y轴对称的...
Given thatf(x)is an even function,g(x)is an odd function andf(x)+g(x)=\frac{1}{x-1}, find the expression off(x). 详解: 由题可知,f(x)+g(x)=1x−1,把-x代入,并根据f(x)与g(x)的奇偶性, f(−x)+g(−x)=f(x)−g(x)=1−x−1, ...

The function g(x) = x3 - 3x is symmetric about the origin and is thus an odd function.Stated another way, functions are even if changing x to -x does not change The value of the function.EVEN FUNCTION: f(x) = x2 - 18f(-x) = (-x)2 - 18 = x2 - 18 Since f(-x) = f...
This function is the sum of the previous two functions. But, while the sum of an odd and an even number is an odd number, I cannot conclude the same of the sum of an odd and an even function. Note that the graph of this function does not have the symmetry of either of the ...
