同学们都知道,判断奇偶性首先要看函数的定义域是否关于原点对称,不对称则是非奇非偶函数,对称后根据f(-x)=f(x)是偶函数,f(-x)=-f(x)是奇函数,否则也是非奇非偶函数,貌似简单,碰到问题我们还是要小心,下面我们看几个例子. Students all know that to determine the parity of the first thing to see whether the domain of the function is symmetric about the origin, asymmetry is a non-odd non-even function, symmetric after f (-x) = f (x) is an even function, f ) = - f (x) is an odd function, or non-odd non-even function, seemingly simple, we still have to be careful with the problem, here we look at a few examples.
