Domain: All real numbers
or

Range: All real numbers
Or

Step-by-step explanation:
The given function is 
This a polynomial function of degree 1.
Polynomial functions are continuous everywhere.
The function is therefore defined for all real values of
.
The domain is 
If we let 
Then,
.
is also defined for all real values of
, hence the range is also all real numbers or
