The domain the function is .
In interval notation: [7, ∞).
The range of the function is in the interval (1, ∞).
The given function is .
The domain is x ≥ and the range is y ≥.
<h3>What is a function?</h3>A technical definition of a function is a relation from a set of inputs to a set of possible outputs where each input is related to exactly one output.
Now,
⇒
Therefore, the domain the function is
The range of the function is the set of all values of y when we substitute the values of x.
Now, for
So, the value of y in the interval (1, ∞).
Therefore, the range of the function is in the interval (1, ∞).
