You can represent any given function in as many different ways as you want.
3^4 or 9^2
It could represent a point whose coordinates do satisfy the requirements of the function.

The expression (4-2)(1-1)(00)(42) does not represent a function in a mathematical sense. A function is defined as a relation where each input corresponds to exactly one output. In this case, the expression simplifies to 2(0)(0)(42), which equals 0, but it does not define a relationship between inputs and outputs in the way that a function does. Therefore, it is not a function.
The unknown variable in that function.
