Which one is a predicate of two variables?
Choose one option.
Show answer
- D. P(x,y)
Explanation
\(P(x,y)\) has two free variables, \(x\) and \(y\), so it is a predicate of two variables. The others have zero or one variable.
Review the concept: Predicate
A predicate \(P(x)\) is an expression with free variables that becomes a proposition when values are assigned to them.
\[P(x,y)\in\{\top,\bot\}\]
