Question 68073
Which real numbers are not in the domain of f(x)? Why aren't they?

{{{ f(x)= ((x+1)/(x+2)) / ((x-3)/(x+4))}}}
----------------
Cannot be -4 as the denominator of the denominator would be undefined.
Cannot be -2 as the numerator of the complex fraction would be undefined.
Cannot be -3 as the denominator of the complex fraction would be undefined.
