Question

Дана функция f(x) =-8x^2+2x-11.Вычисли f(-2)=?​

Answer 1

Ответ: f(-2)=-8*4-4-11=-32-15=-47. Всё просто.

Объяснение:

Answer 2

To find the value of the function f(x) = -8x^2 + 2x - 11 at x = -2, simply substitute x with -2 in the expression and compute the result:

f(-2) = -8(-2)^2 + 2(-2) - 11 = -8(4) - 4 - 11 = -32 - 4 - 11 = -36 - 11 = -47

So, f(-2) = -47.
