A.2x + 4
B. x + 4
C.6x – 4
D. 2x – 4
E.6x + 4
Diketahui h (x) = (x+2)^2 maka h’(3x) adalah…
Jawaban:
turunan
h(x) = (x + 2)²
h(x) = x² + 4x + 4
h’(x) = 2x + 4
maka,
h’(x) = 2x + 4
h’(3x) = 2(3x) + 4
h’(3x) = 6x + 4 [E]
h(x) = (x+2)²
= x² + 4x + 4
h'(x) = 2x²⁻¹ + 4x¹⁻¹
= 2x + 4
h'(3x) = 2(3x) + 4
= 6x + 4
Jawaban : E. 6x + 4
