For this case we have that by definition, the domain of a function, is given for all the values for which the function is defined.
We have:
The given function is not defined when the denominator is equal to zero. That is to say:
To find the roots we factor, we look for two numbers that when multiplied give as a result "8" and when added as a result "-6". These numbers are:
Thus, the factored polynomial is:
That is to say:
Makes the denominator of the function 0.
Then the domain is given by:
All real numbers, except 2 and 4.
Answer:
x |x≠2,4
