Question

Given the relation = {((5,3), (7, −2), (, 6), (−4, −7)}}. What should be the value of so that can be a function?

Answer 1

R is reflexive if it contains (1,1)(2,2)(3,3)

∵(1,2)∈R, (2,3)∈R

∴R is symmetric if (2,1),(3,2)∈R

Now, R={(1,1),(2,2),(3,3),(2,1),(3,2),(2,3),(1,2)}

R will be transitive if (3,1);(1,3)∈R. Thus, R becomes and

equivalence relation by adding (1,1)(2,2)(3,3)(2,1)(3,2)(1,3)(1,2). Hence, the total of ordered pair is 7. mark it as brainlist
