What is the domain and range of the function
1 answer:
Answer:
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
