Algebra-2

Domain:

The domain of the function refers to the set of all possible values of x for which the function is defined.

The expression inside the square root is x - 1, and we cannot take the square root of a negative number in the real number system. Therefore, we require:

x - 1 ≥ 0 ⟹ x ≥ 1

So, the function is defined for all x ≥ 1.

Range:

The range refers to the set of all possible values of as x takes values from the domain.

When x = 1, , so .

As x→+∞,
