1 Answer. Let f:A→B be a map and let S be a subset of B, then the preimage of S under f is f−1(S)={a|f(a)∈S}. For example if A={1,2,3}, B={a,b,c} and f is map defined by f(1)=f(2)=a, f(3)=b, then f−1(∅)=∅,f−1({a})={1,2}, f−1({b})={3}, f−1({c})=∅,f−1({a,b})={1,2,3}, f−1({a,c})={1,2}, f−1({b,c})={3},f−1({a,b,c})={1,2,3}.
