1) For a function to have an inverse, it must be _____________________________.

2) If two functions f and g are inverses, then f composite g = ________________ = x.

3) The domain of f is equal to the ______________________ of f inverse, and the range of f is equal to the ________________ of f inverse.

4) If a point (a,b) lies on the graph of f, and f has an inverse, then the point __________ lies on the graph of f inverse.

5) If a function f has an inverse, then the graph of f inverse may be obtained by reflecting the graph of f across the line with the equation ______________.

Solution

1) one to one

2) g composite f

3) range , domain

4)(b,a)

5) y=x
