Find the domain and the range of the real function f defined by .

Given:

is defined for x≥1.

Hence, the domain of f is the set of all real numbers greater than or equal to 1 i.e., the domain of f = [1, ∞).

As

Hence, the Range of f is the set of all real numbers greater than or equal to 0 i.e., the Range of f = [0, ∞).
