    A function $f$ from the set of natural numbers to integers defined by $f(n)=\left\{\begin{array}{l}\frac{n-1}{2}, \text { when } n \text { is odd } \\ -\frac{n}{2}, \text { when } n \text { is even }\end{array}\right.$ is

    The function f\left ( x \right )= \log \left ( x+\sqrt{x^{2}+1} \right ) is

    Even and Odd Function

    Even function:

    If for a function $f(x), f(-x)=f(x)$ then the function is known as even function. Even functions are symmetric about the $y$ axis.

     

             

                y = x                                           y = |x|                                              y = cos(x)

    Odd function:

    If for a function $f(x), f(-x)=-f(x)$ then the function is known as odd function. Odd functions are symmetric about the origin.

                  

                                    y = sin(x)                                                           y = x3

     

    NOTE: We can have functions that are neither even nor odd. Eg, $\mathrm{y}=\mathrm{x}+1$
