Q12 of 73 Page 126

If then find dom (f) and range (f).

Given,


(i) dom(f)


Here f(x) is a polynomial function whose domain is R except for points at which denominator becomes zero.


Hence x ≠ 5


The domain is (−∞,∞) – {5}


(ii) range(f)


Let


For the specified domain


y = - 1


Range is {-1}.
