Answer:
Range of f=R
Explanation:
We are given that a function

We have to find the range of given function.
The given function is linear function because the degree of function is 1.
When the degree of function is 1 then the function is called the linear function.
The domain of linear function is a set of real numbers because it can be defined for all real values of x.
Domain of given function =R
When we substitute the real value of x in given function then we get a real number also.
Therefore, the range of f=R
