1.

Let f and g be two real functions given by f = {(0, 1), (2, 0), (3, -4), (4, 2), (5, 1)} and g = {(1, 0), (2, 2), (3, -1), (4, 4), (5, 3)}. Find the domain of fg

Answer»

Given,

f = {(0, 1), (2, 0), (3, -4), (4, 2), (5, 1)} and

g = {(1, 0), (2, 2), (3, -1), (4, 4), (5, 3)}

D(f) = {0, 2, 3, 4, 5}

D(g) = {1, 2, 3, 4, 5}

So,

D(fg) = {2, 3, 4, 5}
