2. g(x) = (5-x³)(x²-x)
= x.(5-x³).(x-1)
= x(5x - 5 - x⁴+x³)
g(x) = 5x²-5x-x⁵+x⁴
g'(x) = 10x-5-5x⁴+4x³
g'(x) = -5x⁴+4x³+10x-5
3. f(x) = (4x-6)/(2x+3)
lakukan pembagian metode horner :
4 -6
x = -3/2 -6
4 -12
hasil : f(x) = 4 - 12/(2x+3)
f'(x) = 0 - (-12/(2x+3)² .2)
f'(x) = 24/(2x+3)²
f'(-2) = 24/(2.(-2)+3)²
f'(-2) = 24/(-4+3)²
f'(-2) = 24/(-1)²
f'(-2) = 24
