WebInverse Function. For any one-to-one function f ( x) = y, a function f − 1 ( x) is an inverse function of f if f − 1 ( y) = x. This can also be written as f − 1 ( f ( x)) = x for all x in the domain of f. It also follows that f ( f − 1 ( x)) = x for all x in the domain of f … Web2 Answers. Sorted by: 1. To find the range of the function put x + 1/x =y This will reduce to x^2 +1 -yx=0. Now since x is real therefore the discriminant of the above equation should be Non Negative which gives y^2 - 4 >=0 which gives y>=2 and y<=-2. Hence the range which is y is y>=2 and y<=-2. Share.
