Best ResponseYou've already chosen the best response.0or would that be [0 , 4] only if we consider the radical inside?

Best ResponseYou've already chosen the best response.1hint: the inner radical exists if \[\Large x \geqslant 0\] furthermore we have the subsequent condition: \[\Large 2  \sqrt x \geqslant 0\]

Best ResponseYou've already chosen the best response.1that additional condition, is equivalent to this one: \[\Large 2 \geqslant \sqrt x \]

Best ResponseYou've already chosen the best response.0If we consider both conditions , the inner radical and the whole radical, I need to make the inner radical exist, as well as meeting the subsequent condition, thats the rule right ?

Best ResponseYou've already chosen the best response.0im thinking it should be all real numbers except , x would not equal to 0 and 4

Best ResponseYou've already chosen the best response.1hint: starting from this inequality: \[\Large 2 \geqslant \sqrt x \] square both sides, what do you get?

Best ResponseYou've already chosen the best response.0its [ 0 , 4 ] is it ?

Best ResponseYou've already chosen the best response.1correct! furthermore, as I wrote before, we have: \[\Large x \geqslant 0\] so, what can you conclude?

Best ResponseYou've already chosen the best response.0in overview Im getting the intersection of both conditions right ?
