Question

Найдите производные функции

Answer 1

Ответ:

1.

$y = {x}^{2} \\ y '= 2x$

2.

$y = 1 - {x}^{3} \\ y '= 0 - 3 {x}^{2} = - 3 {x}^{2}$

3.

$y = 3 {x}^{2} - 4x + 5$

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

4.

$y = 4 {x}^{3} - {x}^{5}$

$y' = 4 \times 3 {x}^{2} - 5 {x}^{4} = \\ = 12 {x}^{2} - 5 {x}^{4}$
