Let f and g be two real functions given by
`f={(0,1),(2,0),(3,-4),(4,2),(5,-1)}`
and `g={(1,0),(2,2),(3,-1),(4,4),(5,3)}`
then the domain of `f*g` is given by ..........

Explanation

To find the domain of the composite function \( f \circ g \) (which is often denoted as \( f * g \) in this context), we need to follow these steps:

### Step 1: Identify the Domain of Each Function
First, we need to identify the domains of the functions \( f \) and \( g \).

- For function \( f \):
The pairs given are \( (0,1), (2,0), (3,-4), (4,2), (5,-1) \).
The domain of \( f \) consists of the first elements of these pairs:
...
