carilah turunan pertama,turunan kesua,dan turunan ketiga dari fungsi-fungsi berikut : a) f(x)= 2x4 - x3 +4x2 +2x +8 b). f(x)= (3x +5)5

a) f(x)= 2x4 - x3 +4x2 +2x +8
f'(x) = 8x³-3x²+8x+2
f''(x) = 24x²-6x+8
f'''(x) = 48x-6

b). f(x)= (3x +5)^5
f'(x) = 15(3x+5)⁴
f''(x) = 15.4.3(3x+5)³
= 180(3x+5)²
f'''(x) = 1080(3x+5)
