Turunan fungsi f(x) 2xpangkat2-6 per 4x-7 adalah A. 8xpangkat2-28x-5 per 4x-7 B. (4x-7)pangkat2 per 4(2xpangkat2-5) C. 4x-5 per 4 D. 8xpangkat2-28x+28 per (4x-7

f(x) = (2x² - 6) / (4x - 7)

u = 2x² - 6 --> u' = 4x
v = 4x - 7 --> v' = 4

f'(x) = [u'v - uv'] / v²
f'(x) = [4x(4x - 7) - (2x² - 6)4] / (4x - 7)²
f'(x) = [16x² - 28x - 8x² + 24] / (16x² - 56x + 49)
f'(x) = (8x² - 28x + 24) / (4x - 7)²

f(x) = (2x^2 - 6)/(4x - 7)
u = 2x^2 - 6 => u' = 4x
v = 4x - 7 => v' = 4
f'(x) = (u'.v - u.v')/v^2
f'(x) = [4x(4x -7) - (2x^2 - 6)(4)]/(4x - 7)^2
f'(x) = [(16x^2 - 28x) - (8x^2 - 24)]/[16x^2 - 56x +49]
f'(x) = [16x^2 - 28x - 8x^2 + 24]/[16x^2 - 56x + 49]
f'(x) = [8x^2 - 28x + 24]/[4x - 7]^2
