Here's the Solution to this Question

Solution:

a)

The reflexive closure of a relation R on A is obtained by adding (a, a) to R for each a ∈ A

reflexive closure of R: \{(0,1),(1, 1), (1, 2), (2, 0), (2, 2),(0,0),(3,3)\}


b)

symmetric closure of R is obtained by adding (b, a) to R for each (a, b) ∈ R

symmetric closure of R: \{(0,1),(1, 1), (1, 2), (2, 0), (2, 2),(1,0),(2,1),(0,2)\}
