Answer 1

$1)\; \; y=\sqrt{x}\\\\A(0,01\, ;\, 0,1):\; \; \sqrt{0,01}=0,1\; \; \to \; \; \; \boxed {A\in y(x)}\\\\B(9;-3):\; \; \sqrt{9}=3\ne -3\\\\C(0,144\, ;\, 0,12):\; \; \sqrt{0,144}\approx 0,379\ne 0,12\; \; \Big(\; \sqrt{0,0144}=0,12\; \Big)\\\\D(-1;-1):\; \; \sqrt{-1}\; \; ne\; syshestvyet\; \; \; \Big(\; y=\sqrt{x}\; \; \to \; \; x\geq 0\; \Big)\\\\\\4)\; \; m<0:\; \; \sqrt{16m^{10}}=\sqrt{4^2\cdot (m^5)^2}=4\cdot |m^5|=4\cdot |m|^5=4\cdot (-m)^5=\boxed{-4m^5}$
