Question

Tentukan turunan pertama (turunan fungsi aljabar) :
1. f(x) = 4/x
2. f(x) = -2/x²
3. f(x) = 6x √x
Mohon banget bantuannya .. ^-^

Answer 1

1) f(x) = 4x⁻¹
f ' (x) = - 4x⁻² = - 4/x²

2) f(x) = - 2x⁻²
f ' (x) = 4x⁻³ = 4/x³

3) f(x) = 6x^(3/2)
f ' (x) = 6(3/2)x^(1/2)
        = 9√x

Answer 2

Nomor 1. f(x) = 4/x
             f(x) = 4.x⁻¹
             f'(x) = -4x⁻² = 
nomor 2.
f(x) = -2/x²
f(x) = -2.x⁻²
f'(x) = 4.x⁻³  = 
nomor 3.
f(x) = 6x √x
      = 6.x.
      = 6. 
f'(x) = 9.  = 9√x
