Problem
Solution
For this case we want to find the domain for this case and we can analyze the denominator on this case because cannot be equal to 0, so we can set up this:
If we factorize we got:
(X-3)(x+2)=0
So then we have X=3 and X=-2
With these results we can conclude that the value of x cannot be 3 or -2 because then the function will be not defined
And the best solution is:
A. all real numbers except -2 and 3
