Which real numbers are not in the domain of f(x)? Why aren't they?
+f%28x%29=+%28%28x%2B1%29%2F%28x%2B2%29%29+%2F+%28%28x-3%29%2F%28x%2B4%29%29
----------------
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.
