1.	❤ give one one example of reflexive , symmetric and transitive functions ??
Answer» uge\underline\mathfrak\black{relations }[/textypes of relation ; A relation R in a set A is called 1) reflexive, if (a,a) belongs to R for all A belongs to A2) symmetric: if (a,b) belongs to R ⇨ (b,a) belongs to R ,for all a,b belongs to A3) transitive; if (a,b) belongs to R and (b,a) belongs to R⇨(a,c) belongs to R , for all a,b,c belongs A.example ;• R = { (a,b) : a,b belongs to Z and (a-b) is divisible by 5} • A = {1,2,3,4,5}R = {(a,b) :\|a-b\| is even}
