{a,b,c,d), T₁ = {0, x, (a), (b}, {a,b}, {a,c}, {a,b,c}} {a}, T1 Let X = and T2 {0, X, {a}, {c}, {a,b}, {a,c}, {a,b,c}} be topologies on X. Let F₁ and F2 be the set of all closed sets associated with T₁ and T2 respectively. (a) Write down all the elements for the sets Fi and F2. (b) Find the following and justify whether each of them is a topology or not: i. T1 U T2. ii. T₁ T2. (c) Is there any relationship between either F₁ UF2 or F₁ F2 and the topology identified in 2(b) above?
