Identity Function Graph f(x)=x Domain and Range How to graph, examples

Identity function graph. Identity Function Graph f(x)=x Domain and Range.
By using graphing approach it is very easy to understand properties of identity function f(x)=x, like domain and range of identity function, slope of identity function, continuity and differentiability of identity function in its domain. So, I hope this will help you. Thanks.

After watching this lecture, you will be able to answer the following questions:-

(a) What is identity function or What is definition of identity function?
(b) Other names of identity function or Identity Relation, Identity Map, Identity Transformation.
(c) How to plot graph of identity function?
(d) How to find domain and range of identity function?
(e) Is the graph of identity function a straight line?
(f) What is slope of curve represented by identity function?
(g) Graph of f(x)=x
