If the function is f(x)=1/(6x+6) then the value of x cannot be equal to -1.
Given a function of x f(x)=1/(6x+6).
We are told to find out the value of the variable x for which the function does not lie.
Function is like a relationship between two or more variables expressed in equal to form. The values entered in a function is known as domain and the values which we get after entering of values are known as range.
f(x)=1/(6x+6)
It is in form of fraction. Fraction is a combination of numbers in which the above number is numerator and below number is denominator.
In this (6x+6) cannot be equal to 0 because if (6x+6) equal to 0 then the value of function becomes infinity.
So,
6x+6=0
6x=-6
x=-1
Hence if the function is f(x)=1/(6x+6) then the value of x cannot be equal to -1.
