Answer : (i) domain

As f(x) is a polynomial function whose domain is R except for the points where the denominator becomes 0.

Hence x≠ Domain is R-{ }

(ii) Range

Let y=

Y(bx-a) = ax +b byx -ay = ax + b byx -ax= ay +b x(by -a) = ay + b

x =

x is not defined when denominator is zero. by – a ≠ 0

y≠a/b

Range is R-{a/b}.
