Explanation Given information: f ( x ) = x 2 x 2 − 1 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 To determine (b) If f ( x ) = x 2 x 2 − 1 then find the inverse function for f in [ 0 , ∞ )
