(a) x x = 1 2 , x = 7 (b) x x = 1 3 , x = 1 2 (c) x x = 2 , x = 1 2 (d) x x = 1 3 (e) x x = 1 3 , x = 2 (f) Domain is all real num- bers. 2. Find the inverse function of f ( x ) = 2 x- 1 x + 1 . State the domain and range of f ( x ). (a) f- 1 ( x ) =- x + 1 x- 2 ; domain of f ( x ) = { x | x =- 1 } ; range of f ( x ) = { y | y = 2 } (b) f- 1 ( x ) =- x + 1 x- 2 ; domain of f ( x ) = { x | x = 2 } ; range of f ( x ) = { y | y =- 1 } (c) f- 1 ( x ) = x + 1 2 x- 1 ; domain of f ( x ) = { x | x =- 1 } ; range of f ( x ) = y y = 1 2 (d) f- 1 ( x ) = x + 1 2 x- 1 ; domain of f ( x ) = x x = 1 2 ; range of f ( x ) = { y | y =- 1 } (e) f- 1 ( x ) =- x- 1 x + 2 ; domain of f ( x ) = { x | x =- 1 } ; range of f ( x ) = { y | y =- 2 } (f) f- 1 ( x ) =- x- 1 x + 2 ; domain of f ( x ) = { x | x...
