Question

Найди значение функции y(x)=3x3+3x при x=3a.​

Answer 1

Ответ:

y(3a)=3*3a+3*3a

y(3a)=18a²

Answer 2

To find the value of the function $y(x)=3x^3+3x$ at $x=3a$, simply substitute $3a$ into the function and compute the result:

$y(3a) = 3(3a)^3 + 3(3a)$

Now, simplify the expression:

$y(3a) = 3(27a^3) + 9a$

$y(3a) = 81a^3 + 9a$

So, the value of the function $y(x)=3x^3+3x$ at $x=3a$ is $81a^3 + 9a$.
