Identity Function |
f(x)=x Domain and range are both R |
|
|
Constant function |
f(x)=C (Constant) Domain is R and range is {C} |
|
|
Polynomial function |
The graph will vary depending on the polynomial. |
|
|
Rational function |
Its of the type f(x)/g(x), where f(x) and g(x) are polynomial functions of x defined in a domain, where g(x)≠0. |
|
|
Modulus function |
|x|and|-x| are both equal to x. f(x)=y=|x| |
|
|
Signum function |
f(x)= 1, if x>0 0, if x=0 -1, if x<0. Domain is R and range is the set {-1,0,1}. |
|
|
Greatest integer function |
For example, [x]=1 for 1 _<x<2 because 1 is the greatest no. to 1 which is smaller than or equal to 1. If it had been [x]= 1.3, then also it would be 1. The circles at the end of the line represent exclusion of 2 as [x]=1 for 1 _<x<2. |
