What is the domain of f (x) = √x + 2?

A. all real numbers greater than or equal to 2

B. all real numbers

C. all real numbers greater than or equal to 0

D. all real numbers greater than 0

Domain is numbers you can use

we can't use numbers that cause problems

numbers that make division by zero and sqar roots of negative numbers

f (x) = √x+2

x cannot be negative

x can equal zero, that results in zero

√0=0

domain=all real numbers greater than or equal to 0
