What is the domain and range of the function

Option d is correct.

Domain = all real number

range = positive real numbers

Step-by-step explanation:

Given the function:

Domain of the function is all real numbers except where the expression is undefined.

In this case, there is no real number that makes the expression undefined.

Domain of f(x) = = {a | a∈R}

Range is the set of all valid  f(x) values.

Therefore, Domain is all real number and the range of function is positive real number
