Soal :
f : x --> 1/4 (3-x)
g daerah asal [-2, -1, 0, 1]
Tentukan daerah hasil!

Answer 1

Verified answer

Daerah asal {-2, -1, 0, 1}

f(x) = ¼ (3 - x)

f(-2) = ¼ (3 - (-2))
f(-2) = 5/4

f(-1) = ¼ (3 - (-1))
f(-1) = 1

f(0) = ¼ (3 - 0)
f(0) = ¾

f(1) = ¼ (3 - 1)
f(1) = ½

daerah hasil {5/4, 1, ¾, ½}
