Постройте по точкам график функции \(\displaystyle y=-0{,}3x^2{\small :}\)

\(\displaystyle x\)	\(\displaystyle -3\)	\(\displaystyle -2\)	\(\displaystyle -1\)	\(\displaystyle 0\)	\(\displaystyle 1\)	\(\displaystyle 2\)	\(\displaystyle 3\)
\(\displaystyle y\)	[ ]	[ ]	[ ]	[ ]	[ ]	[ ]	[ ]

Двигая ползунки \(\displaystyle a\) и \(\displaystyle b{ \small ,}\) постройте точки графика \(\displaystyle y=-0{,}3(x+1)^2-2{\small .}\)

Запишите полученные координаты точки

\(\displaystyle \color{green}{S}=(\)[ ]\(\displaystyle ;\)[ ]\(\displaystyle )\)

c точностью до десятых.
