Question

A binary operator f on a set X is commutative if f(x, y) = f(y, x)
for all x, y ∈ X.State whether the given
function f is a binary operator on the set X. If f is not a binary
operator, state why. State whether or not each binary operator is
commutative

f(x, y) = x ∪ y, X = P({1, 2, 3, 4})

f(x, y) = xUy, X = P({1, 2, 3, 4})
Transcribed Image Text:f(x, y) = xUy, X = P({1, 2, 3, 4})
