Answer 1

$\displaystyle\bf\\1)\\\\y=\frac{1}{3} x^{2} \\\\\\x\ion\Big[-3 \ ; \ 6\Big]\\\\\\y(-3)=\frac{1}{3} \cdot(-3)^{2} =\frac{1}{3} \cdot 9=3\\\\\\y(6)=\frac{1}{3} \cdot 6^{2} =\frac{1}{3} \cdot 36=12\\\\\\Otvet \ : \ E(y)=\Big[3 \ ; \ 12\Big]\\\\2)\\\\y=-\frac{1}{4} x^{2} \\\\\\x\ion\Big[-2 \ ; \ 8\Big]\\\\\\y(-2)=-\frac{1}{4} \cdot(-2)^{2} =-\frac{1}{4} \cdot 4=-1\\\\\\y(8)=-\frac{1}{4} \cdot 8^{2} =-\frac{1}{4} \cdot 64=-16\\\\\\Otvet \ : \ E(y)=\Big[-16 \ ; \ -1\Big]$
