Question

Найдите производную функции

Answer 1

а) $f'(x)=x^2+2x+2$

======================

б) $y'(x)=- frac{6}{x^4} -1$

======================

в) $g'(x)=4cosx \ g'(- frac{2 pi }{3} )=g'(frac{2 pi }{3} )=4cos(frac{2 pi }{3} )=-2$

======================

г) $h'(x)= frac{-3x(x+2)-(2-3x)}{(x+2)^2} = frac{-3x^2-6x-2+3x}{(x+2)^2} =- frac{3x^2+3x+2}{(x+2)^2} \ \ h'(-1)= -frac{3-3+2}{1} =-2$
