Definition of Function
A function is a term used to define relation between
variables.
A variable  y is called a function of a variable x if
for every value of x there is a definite value of y.
Symbolically y = f(x)
We can assign values of x arbitrarily. So x is called
independent variable whereas y is called the dependent
variable as its values depend upon the value of x.

Types of Functions
1. Even Function – A function f(x) is said to be even
function if
f(-x) = f(x)
e.g. f(x) = 2x
2
+ 4x
4

f(-x)  = 2(-x)
2
+ 4(-x)
4

= 2x
2
+ 4x
4
= f(x)
Hence 2x
2
+ 4x
4
is an even function.

2. Odd Function – A function is said to be odd function if
f(-x) = - f(x)
e.g. f(x) = 3x + 2x
5

f(-x)  = 3(-x) + 2(-x)
5

= -3x - 2 x
5

= - (3x + 2 x
5
) = - f(x)
Hence 3x + 2 x
5
is an odd function.
