In order for f–1(x) to be a function, the domain of f(x) can be restricted to
.

Under this restriction, the domain of f–1(x) would be
, having the same minimum value as the
.

Answer 1

In order for f⁻¹(x) to be a function, the domain of f(x) can be restricted to x ≥ 1.

Under this restriction, the domain of f⁻¹(x) would be [2, ∞), having the same minimum value as the range of f(x) (minimum = 2).
