- You just bought a new car from a dealership that sells cars no older than 2015. Consider therelationship to be the “same age.” The relation is “same age” and the set is cars made in 2015, 2016,2017, 2018, 2019, and 2020. (a) Prove that this relation is an equivalence relation. (b) Describe the partition defined by the equivalence classesarrow_forward(a) Give complete definitions of the terms (i) Cartesian product of two sets; (ii) relation on a set; (iii) equivalence relation on a set. (b) Write down examples of: (i) a relation which is transitive but not reflexive; (ii) an equivalence relation on {1, 2, 3, 4} with exactly three equivalence classes. (c) Let X and Z be any two sets, and f : X - → Z any function. Prove that {(x, y) = X²: f(x) = f(y)} is an equivalence relation on X.arrow_forwardHow do i solvearrow_forward
