Question

Найдите значение функции y=x-3x^2-6 при x=-2

Answer 1

Подставляем значение х
у= -2-3(-2^2)-6
у= -2 -12 -6
у= -20
Ответ: -20

Answer 2

To find the value of the function $y = x - 3x^2 - 6$ when $x = -2$, we simply substitute $x = -2$ into the expression and calculate $y$.

$y = (-2) - 3(-2)^2 - 6$

Now, let's perform the calculations step-by-step:

$y = -2 - 3 \times 4 - 6$

$y = -2 - 12 - 6$

$y = -20$

So, when $x = -2$, the value of the function $y$ is $-20$.
