Найти f `(x0) , если f(x) = (4x+3)^6 , x0= -1

Question

Найти f `(x0) , если f(x) = (4x+3)^6 , x0= -1

Answer 1

Найдем производную

f ' (x) = 6 (4x + 3)^5 (4x + 3) ' = 24 (4x + 3)^5 

f ' (-1) = 24* ( - 4 + 3)^5 = 24 * (-1)^5 = - 24

Answer 2

F` = 6*4*(4x+3)^5 = 24(4x+3)^5
f`(-1) = 24(-1)^5 = -24
