Unformatted text preview: f o f1 = f f1 (29 = x f1 o f = f1 f (29 = x Problem. Find the inverse function of fx (29 = x5 . Solution. y = x5 y 2 = x5 x = y 2 + 5 y = x 2 + 5 f1 x (29 = x 2 + 5 Problem. Find the inverse function of f x ( 29 = x2 x + 5 . Solution. y = x2 x + 5 x + 5 ( 29 y = x2 xy + 5 y = x2 xyx =5 y2 y1 ( 29 x =5 y2 x =5 y2 y1 y =5 x2 x1 f1 x (29 =5 x2 x1 Problem. Find the domain and range of the inverse function for fx (29 = 3 + 7 x . Solution. Domain of the function is 3 + 7 x ≥ , or x ≥3 7 , so 3 7 , ∞ . Range of the function is 0, ∞ [ 29 . Therefore, domain of the inverse function is 0, ∞ [ 29 . Range of the inverse function is 3 7 , ∞ ....
