Which function's domain consists of all real numbers except -2?

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

d
