So, excluded value is the value which can make the denominator 0..
As, you know denominator must not be 0, that is why this value is to be excluded and is called Excluded Value..

So, you have to just put your Denominator = 0:
And then find x from it:
\[4x - 8 = 0\]
Find x here..

set the denominator = 0, so 4x - 8 = 0
so 4x = 8. Now find the value of x. and this x value will be the excluded value as you cant use the x you find for this equation.
