How do you find the domain and range of #f(x)= (3x-1)/((x+3)(x-1))#?

Question:

How do you find the domain and range of #f(x)= (3x-1)/((x+3)(x-1))#?

Answers

Domain = #RR-{-3,1}.#

Range =#RR.#

Explanation:

We know that division by zero is not permissible, so, fun. #f# will not be defined when #x+3=0,# i.e., when #x=-3,# and #x=1,# as well.

so, the Domain of #f# is #RR-{-3,1}.#

Range is #RR.#
