Answer:

Choice A

Explanation:

A restriction of just a point is a hole, which means it is in the denominator

To determine this, we look at the denominators,

B and C do not have denominators,

Square roots cannot be negative, so they have larger restrictions

for D x+2 ≥0

x≥-2

Choice A is the only option that has a restriction that is a hole

x+2 ≠0

x≠-2
