the domain for f(x) is all real numbers. (Blank) than or equal to 3

Answer:
greater
Step-by-step explanation:
The domain is the number that x can be
sqrt(x-3) must be greater than or equal to zero
x-3 must be greater than or equal to zero
x must be greater than or equal to three
The other restriction is x+2 cannot equal zero
x cannot equal -2
The first restriction is more restrictive so that is the one we go with
