In this case we have to simplify the expression by giving it in the standard polynomial format, first we have to see what is the polynomial standard format, this is:
In the case of the expression presented we have to make the multiplications and additions to then organize the expression:
First the multiplications:
Now the additions and organization:
Now we have the expression in the polynomial format.
as the function is polynomial domain exist for all real number ie (-infinity to + infinity) but range exist (0 to +infinity ) due to modulus negetive range do not exist
