Question

What are the possible values of x for the following functions?

f(x)= 3x/(x−1)(x−2)

Answer 1

Given : f(x)= 3x/(x−1)(x−2)

To Find :  possible values of x for the following functions

Solution:

f(x)= 3x/(x−1)(x−2)

f(x) is not defined  if denominator is zero

(x - 1)(x - 2) =0

=> x = 1 , x = 2

Hence f(x)= 3x/(x−1)(x−2)  is not defined for x = 1 & 2

possible values of x for the f(x)= 3x/(x−1)(x−2)

= R - { 1 , 2}
