Answer:
Choice A
Step-by-step 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
