Let f : R R : f(x) =x2 and g : C C: g(x) =x2, where C is the set of all complex numbers. Show that f ≠ g.

It is given that f : R R and g : C C

Thus, Domain (f) = R and Domain (g) = C


We know that, Real numbers ≠ Complex Number


, Domain (f) ≠ Domain (g)


f(x) and g(x) are not equal functions


f ≠ g
