Verified answer

Nomor 12)

f(x) = 6x³ - 8x² + 5x - 13
f'(x) = 18x² - 16x + 5
f'(2) = 18(2)² - 16(2) + 5
       = 18(4) - 32 + 5
       = 72 - 32 + 5
       = 45

nomor 13)

y = (4x + 3)^5
y' = 5(4x + 3)^4.4
    = 20(4x + 3)^4

nomor 14)

f(x) = (x - 1)²(x + 1)
u = (x - 1)²
u' = 2(x - 1)
v = (x + 1)
v' = 1

f'(x) = vu' + uv'
       = (x + 1)2(x - 1) + (x - 1)²(1)
       = 2(x² - 1) + (x - 1)²
atau
       = (x - 1) ((2x + 2) + (x - 1)
       = (x - 1) (3x + 1)
