problem
determine the domains of (a) \(\displaystyle f\), (b)\(\displaystyle g\), and (c) \(\displaystyle f \cdot g\)
\(\displaystyle f(x) = \sqrt{x+4} , g(x) = x^2\)
domain of f - any real number except -4 since the answer will be 0
domain of g - shouldn't the answer be any real number except 0? I don't understand why 0 is included in domain
Can someone elaborate this problem to me please?
