Let f : R <span l

Answer :

Given f : R R f(x) = x2 and g : R R g(x) = x2


As f is defined from R to R, the domain of f = R.


As g is defined from C to C, the domain of g = C.


Two functions are equal only when the domain and codomain of both the functions are equal.


In this case, the domain of f ≠ domain of g.


Thus, f and g are not equal functions.
