The value of f(0) is 1
Explanation:
Given that the coordinates are
,
,
and 
We need to determine the value of f(0)
Using the coordinate
, we shall determine the function.
For
, the function is 
Similarly, using the coordinate
, we shall determine the function.
For
, the function is 
Using the coordinate
, we shall determine the function.
For
, the function is 
Using the coordinate
, we shall determine the function.
For
, the function is 
Therefore, the value of f(0) is 1
