Your question is a little ambiguous, but I am assuming that you meant to say the function
Thus, I am solving your question based on assuming the function such as
But, it would still clear your concept, no matter what the function is.
Answer:
we conclude that
The graph is also attached.
Step-by-step explanation:
Given the function
We know that the domain of a function is the set of input or argument values for which the function is real and defined.
As the function has no undefined points nor domain constraints.
Thus, the domain is
Therefore, we conclude that
The graph is also attached.
