Explanation Given information: g ( x ) = { − x 2 when x < 0 x 2 when x ≥ 0 Concept used: One-to-One function:- A function f is one-to-one on a domain D if, for every value c, the equation f ( x ) = c has at most one solution for x ∈ D . Or, equivalently, if for all a , b ∈ D , if a ≠ b , then f ( a ) ≠ f ( b ) Inverse: - Let f have domain D and range R. If there is a function g with domain R such that g ( f ( x ) ) = x for x ∈ D and f ( g ( x ) ) = x for x ∈ R then f is said to be invertible. Calculation: g ( x ) = { − x 2 when x < 0 x 2 when x ≥ 0
