Answer 1

$f(x) = ( {x}^{2} - 5)(x - 3) \\ {f}^{1} (x ) = {x}^{3} - 3 {x}^{2} - 5x + 15 = \\ 3 {x}^{2} - 6x - 5 \\ {f}^{1} (x _{0}) = 3 \times {1.1}^{2} - 6 \times 1.1 - 5 = \\ 3.63 - 6.6 - 5 = - 7.97$

Answer 2

Объяснение:

f(x) = x^3 - 3x^2 - 5x +15

f°(x) = 3x^2 - 6x - 5

f°(1.1) = 3·1.1^2 - 6·1,1 -5 = 3·1,21 - 6,6 -5 = -7,39
