for the value of we have the function f(x) = 1/(x-2) or
as undefined or not defined .
<u>Step-by-step explanation:</u>
<u>Function undefined: </u> A function is undefined when it gives results which are not defined for example , infinity .
Here we have , Function f(x) = 1/(x-2) or . We need to find a value of for which this is not defined . Let's find out:
We can clearly see that it's a fractional function with numerator as 1 and denominator as x-2 . For a fractional function to be undefined it's denominator must be zero i.e. x-2 = 0 or

Therefore, for the value of we have the function f(x) = 1/(x-2) or
as undefined or not defined .
