If the domain of the square root function f(x) is x57, which statement must be true?
7 is subtracted from the x-term inside the radical,
The radical is multiplied by a negative number,
7 is added to the radical term,
The x-term inside the radical has a negative coefficient

If f(x) = √x, as the question statement seems to say, then the domain is not x<7.  Rather, the domain is x≥0.  

If f(x) is not the square root function, but say f(x) = √(7-x) then the domain is x≤7, and for this function then the

i don't know, but that looks pretty bad. my school passed us unless we failed in all the subjects, but idk abt ur school's rules.
