Let `f = {(1, 2), (2, 3), (0, 1), ( -1, 0)}`be a linear function from Z into Z. Find f(x).

Explanation

To find the linear function \( f(x) \) given the set of ordered pairs \( f = \{(1, 2), (2, 3), (0, 1), (-1, 0)\} \), we will follow these steps:

### Step 1: Understand the form of a linear function
A linear function can be expressed in the form:
\[ f(x) = ax + b \]
where \( a \) and \( b \) are constants.
