I already know that the domain is (-4, infinity)

littlebird · Answer

Since x is in the denominator and under a square root, the y can never be negative or 0.

jhannybean · Answer

Well, if x=0, y = $\frac{1}{2}$

@Littlebird wrote earlier: "Since x is in the denominator and under a square root, the y can never be negative or 0." This is correct. If y is not negative or zero, then y is non-negative.
