Use the following definitions to express each union or intersection given. You can use roster or set builder notation in your responses, but no set operations. A₁ = {iº, i¹, i²} (Recall that for any number x, xº = 1.) B₁ = {x € R: -i≤x≤1/i} • C₂ = {x € R: -1/i≤ x ≤ 1/i} (a) (b) (c) (d) (e) (f) ni-2 Ai U₁-2 Ai Bi U Bi nC; UD C₂ =1 Use the following definitions to express each union or intersection given.
