Answer 1

$y=\sqrt{x}\\\\a)\ \ A(a;3\sqrt6)\ \ \to \ \ y(a)=3\sqrt6\ \ ,\ \ \sqrt{a}=3\sqrt6\ \ ,\ \ a=9\cdot 6\ \ ,\ \ a=54\\\\b)\ \ x\in [\ 0\, ;\, 36\ ]\ \ \to \ \ \sqrt{x} \in [\ \sqrt0\, ;\, \sqrt{36}\ ]\ \ ,\ \ y\in [\ 0\, ;\, 6\ ]\\\\c)\ \ y\in [\ 13\, ;\, 17\ ]\ \ \to \ \ \sqrt{x}\in [\ 13\, ;\, 17\ ]\ \ ,\ \ x\in [\ 169\, ;\, 289\ ]\\\\d)\ \ y\leq 2\ \ \to \ \ 0\leq \sqrt{x} \leq 2\ \ ,\ \ 0\leq x\leq 4\ \ ,\ \ x\in [\ 0\, ;\, 4\ ]$
