    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
