解一道英语的数学题,rational function!只用把三个式子列出来就好!
Give an example of a rational function with (A) even symmetry (B) odd symmetry (C)
neither even or odd symmetry.Include both the function’s equations and a nice graph.For all of
your examples both the degree of the numerator and the degree of the denominator must be
more than two when the expression is fully reduced.

给出以下情形时的有理函数的例子各一,要求包括函数方程和一个漂亮的图:
(A)偶函数
(B)奇函数
(C)非奇非偶函数
所有给出的例子中分子和分母既约后的次数必须均高于2次
answer:
case A:f(x) = (x²+1) / (x^4 + 1)
case B:f(x) = x^3 / (x^4 + 1)
case C:f(x) = (x²+1) / (x^3 + 1)
画图用Matlab或GeoGebra之类的画一下就行了

rational function 有理函数一般是两个多项式的除法
(A)偶函数 x^4/(1+x^4)
(B)奇函数 x³/(1+x^4)
(C)非奇非偶函数 (1-x+x^3)/(1+x+x^4)
