turunan pertama dari f(x) = 1/2x^4 + 2/3x^3 - 4x + 1 adalah....

[tex]\displaystyle f(x)=\frac12x^4+\frac23x^3-4x+1\\\\f'(x)=\frac12\cdot4x^{4-1}+\frac23\cdot3x^{3-1}-4\cdot1x^{1-1}\\f'(x)=2x^{3}+2x^{2}-4x^{0}\\\boxed{\boxed{f'(x)=2x^{3}+2x^{2}-4}}[/tex]

f(x) = 1/2x⁴ + 2/3x³ - 4x + 1
f(x) = 2x`⁴ + 2.3x`³ - 4x + 1

turunan
f'(x) = -8x^-5 + (-18x`⁴) - 4
f'(x) = -8/x^5 - 18/x⁴ - 4
f'(x) = - (8/x^5 + 18/x⁴ + 4)

semoga berguna +_+
