Best ResponseYou've already chosen the best response.3what is the domain of that second function?

Best ResponseYou've already chosen the best response.3for example I consider the subsequent function: f(x)= sqrt(4x) Now the radical exists, if and only if the subsequent condition holds: \[4  x \geqslant 0 \Rightarrow x \leqslant 4\] am I right?

Best ResponseYou've already chosen the best response.3so that part of function is defined inside this interval of the real line: \[0 \leqslant x \leqslant 4\]

Best ResponseYou've already chosen the best response.3since, from your definition sqrt(4x) is given for all x such that they are greater or equal to zero

Best ResponseYou've already chosen the best response.3now, please do the same with the other part of your function, namely f(x)=sqrt(4+x)

Best ResponseYou've already chosen the best response.3hint: from your definition we have x<0, furthermore, the radical exists if and only if \[4 + x \geqslant 0\] so, what do you get?

Best ResponseYou've already chosen the best response.3please note that in order to draw the graph of your function, we need to know its domain
