Draw with labels, Set name, Domain, Co$-$domain, and arrows and then Determine whether each set in Exercises $10-12$ is a function from $x=\{1,2,3,4\}$ to $Y=\{a,b,c,d\}.$

If it is not a function, explain why

$10.\{(1,c),(2,d),(3,a),(4,b)\}$

$11.\{(1,d),(2,d),(4,a)\}$

$12.\{(1,b),(2,b),(3,b),(4,b)\}$
