The plural 's' at the end means there are more than one. If there are more than one there can be no single formula.
A formula or an expression.
No, it is not. A function can only have one output per input. (If it has more than one, it is still maths, but it cannot be called a "function". It would probably be called an equation or a formula etc...).
