\[\boxed{\text{270.}\text{\ }еуроки - ответы\ на\ пятёрку}\]
Пояснение.
Аргумент (x) – это независимая переменная.
Функция (y) – зависимая от x переменная.
Решение.
\[\mathbf{Подставим\ в\ функцию\ вместо\ }\]
\[\mathbf{\text{x\ }}\mathbf{число\ и\ найдем\ }\mathbf{\text{y.}}\]
\[x\] | \[- 5\] | \[- 4\] | \[- 3\] | \[0\] | \[2\] | \[3\] | \[6\] |
---|---|---|---|---|---|---|---|
\[y\] | \[16\] | \[7\] | \[0\] | \[- 9\] | \[- 5\] | \[0\] | \[27\] |
\[x = - 5 \Longrightarrow \ \ y = ( - 5)^{2} - 9 =\]
\[= 25 - 9 = 16.\]
\[x = 3 \Longrightarrow \ \ y = 3^{2} - 9 = 9 - 9 =\]
\[= 0.\]
\[x = - 3 \Longrightarrow y = ( - 3)^{2} - 9 =\]
\[= 9 - 9 = 0.\]
\[x = - 4 \Longrightarrow y = ( - 4)^{2} - 9 =\]
\[= 16 - 9 = 7.\]
\[x = 0 \Longrightarrow y = 0^{2} - 9 = - 9.\]
\[x = 2 \Longrightarrow y = 2^{2} - 9 = 4 - 9 =\]
\[= - 5.\]
\[x = 6 \Longrightarrow y = 6^{2} - 9 =\]
\[= 36 - 9 = 27.\]
