Jika f(x) = 3x⁴-2x³+x+2, Maka f'(2) = A.72 B.73 C.74 D.75 E.81

f(x) = 3x^4 - 2x^3 + x + 2
turunannya
f'(x) = 12x^3 - 6x^2 + 1

f'(2)
= 12 . 2^3 - 6 . 2^2 +1
= 12 . 8 - 6 . 4 + 1
= 96 - 24 + 1
= 73

note :
jika f(x) = ax^n
maka
f'(x)
= n . ax^(n-1)

F'(x): 12x*3-6x*2+1
F'(2) :12(2)*3-6(2)*2+1
F'(2): 96-24+1
F'(2): 73
