Question

Помогите пж очень срочно​

Answer 1

Ответ:

$f(x) = - 3 {x}^{3} - 10x + 4$

x0=2

$f(x_{0}) = - 3 \times {2}^{3} - 10 \times 2 + 4 \\ f(x_{0}) = - 3 \times 8 - 20 + 4 \\ f(x_{0}) = - 24 - 16 \\ f(x_{0})= - 40$

x=-1

$f(x) = - 3 \times {( - 1)}^{3} - 10 \times ( - 1) + 4 \\ f(x) = - 3 \times ( - 1) + 10 + 4 \\ f(x) = 3 + 10 + 4 \\ f(x) = 17$
