jwb yg jujur pakek cara kak pls, poinya bnyk itu​

Answer 1

Penjelasan dengan langkah-langkah:

turunan fungsi aljabar

f(x) = (x - 3)/(3x + 2)

misalkan:

u = x - 3 -----> u' = 1

v = 3x + 2 -----> v' = 3

maka:

f'(x) = (u'v - v'u)/v²

f'(x) = {1(3x + 2) - 3(x - 3)}/(3x + 2)²

f'(x) = (3x + 2 - 3x + 9)/(3x + 2)²

f'(x) = 11/(3x + 2)²

f'(-1) = 11/{3(-1) + 2}²

f'(-1) = 11/(-3 + 2)²

f'(-1) = 11/(-1)² = 11/1 = 11
