Best ResponseYou've already chosen the best response.2Hint: You cannot take the square root of a negative number (and get some real number)

Best ResponseYou've already chosen the best response.2So the radicand (the stuff inside the square root) can't be negative

Best ResponseYou've already chosen the best response.2Similar example: Find the domain of \[\Large g(x) = \sqrt{x+3}\] You can't take the square root of a negative number, so the radicand must be either 0 or positive. So... \[\Large x+3 \ge 0\] \[\Large x+33 \ge 03\] \[\Large x \ge 3\] is the domain

Best ResponseYou've already chosen the best response.2yes exactly, so whatever number that is in the square root is either a) zero or b) positive

Best ResponseYou've already chosen the best response.0if your finding the domain of a square root your rules are that the number cant be negative. if you were taking the domain of a fraction the rules would be you cant have a zero on the denominator
