16. Jika π(π₯) = π₯ β 3 dan π(π₯) = 2π₯^2 + 5π₯, maka berapakah nilai dari (π/π)(2)?
a. 5/16
b. 8/16
c. 1/18
d. β1/18
e. β5/16
Jawaban :
π(π₯) = π₯ β 3
π(π₯) = 2π₯^2 + 5π₯
(π/π)(2) ?
(π/π)(2) = f(2) / g(2)
sehingga kita perlu mencari f(2) dan g(2) terlebih dahulu
π(π₯) = π₯ β 3
f(2) = 2 - 3
(π/π)(2) = f(2) / g(2)
(π/π)(2) = - 1 / 18
Jawaban : D
