Bantu jawab besok di kumpulkan

Penjelasan dengan langkah-langkah:

Diketahui

f (x) = 3 – 2x

domain { x I x ≤ 5, x bilangan asli},

= { 1,2,3,4,5}

Ditanya Range ?

Jawab

f(x) = 3 – 2x

f(1) = 3 – 2(1) = 3 – 2 = 1

f(2) = 3 – 2(2) = 3 – 4 = -1

f(3) = 3 – 2(3) = 3 – 6 = -3

f(4) = 3 – 2(4) = 3 – 8 = -5

f(5) = 3 – 2(5) = 3 – 10 = -7

Jadi Range nya { 1,-1,-3,-5,-7}

Pasangan berurutan { (1,1)(2,-1)(3,-3)(4,-5)(5,-7)

Semoga membantu dan tidak keliru
