Answer:

x > -2, or (-2, infinity)

Explanation:

Alexis, all inputs to the natural log function y = ln x must be greater than zero.

Looking at the given y = ln (x + 2), we see that (x + 2) must be greater than zero for the reason given above.

Thus, the domain of y = ln (x + 2) is x + 2 > 0, or (by subtracting 2 from both sides) x > -2, or (-2, infinity)
