Question

bismillah tolong bantu ya,

daerah asal dari fungsi f(x)
x-4
___
x+2 , x € R

dengan rumus domain nya yaa,, tolong banget bentar lagi mau ujian

Answer 1

Jawaban:

Jika diketahui f(x) = 2x - 3

Daerah asal {x Ι x ≤ 6, x ∈ Bilangan Cacah} = {0, 1, 2, 3, 4, 5, 6}

Jika :

x = 0 ⇒ f(0) = 2(0) - 3 = 0 - 3 = - 3

x = 1 ⇒ f(1) = 2(1) - 3 = 2 - 3 = - 1

x = 2 ⇒ f(2) = 2(2) - 3 = 4 - 3 = 1

x = 3 ⇒ f(3) = 2(3) - 3 = 6 - 3 = 3

x = 4 ⇒ f(4) = 2(4) - 3 = 8 - 3 = 5

x = 5 ⇒ f(5) = 2(5) - 3 = 10 - 3 = 7

x = 6 ⇒ f(6) = 2(6) - 3 = 12 - 3 = 9

maaf ya kalau salah
