Answer:The domain of the function y = log3(x + 4) consists of all real numbers x for which the argument of the logarithm, (x + 4), is positive. Since a logarithm is only defined for positive arguments, we set the inequality x + 4 > 0. Solving this, we find x > -4. Therefore, the domain of the function is all real numbers greater than -4.Step-by-step explanation:
