Given, f = {(1, 6), (2, 5), (4, 3), (5, 2), (8, –1), (10, –3)}

g = {(2, 0), (3, 2), (5, 6), (7, 10), (8, 12), (10, 16)}

(1) Domain of f ={1,2,4,5,8,10}

Domain of g ={2,3,5,7,8,10}

Domain of (f+g)= {x : x ∈D f ∩ Dg }

where Df = Domain of function f, Dg = Domain of function g

Domain of (f+g)={2,5,8,10}.

(2) Domain of quotient function f/ g = {x : x ∈D f ∩ Dg and g (x) ≠ 0}

Domain of (f/g) = {2,5,8,10}.
