Step-by-step explanation:
There are four odd number between 1 and 7:
1, 3, 5, 7
So the probability that a randomly selected ball is an odd number is 4/7.
Using the property of inverse,
![f^{-1}(f(x))=x](https://tex.z-dn.net/?f=f%5E%7B-1%7D%28f%28x%29%29%3Dx)
, we can extend the given table
x f(x) f^(-1)(f(x))
-1 1 -1
2 3 2
![f^(-1)(3)=f^{-1}(f(2))=2](https://tex.z-dn.net/?f=f%5E%28-1%29%283%29%3Df%5E%7B-1%7D%28f%282%29%29%3D2)
3 6 3
5 7 5
7 8 7
