fungsi f(x)=9-2x dengan daerah asal {0,1,2,3,4,5}, himpunan daerah hasilnya adalah

f(0) = 9-2.0
= 9
f(1) = 9-2.1
= 7
f(2) = 9-2.2
= 5
f(3) = 9-2.3
= 3
f(4) = 9-2.4
= 1
f(5) = 9-2.5
= -1

Jadi Daerah hasil {9,7,5,3,1,-1}
jadikan jawaban terbaik..

f(x) = 9 - 2x
Daerah asal = {0,1,2,3,4,5}

Daerah hasil
f(0) = 9 - 2(0)
f(0) = 9
f(1) = 9 - 2(1)
f(1) = 7
f(2) = 9 - 2(2)
f(2) = 5
f(3) = 9 - 2(3)
f(3) = 3
f(4) = 9 - 2(4)
f(4) = 1
f(5) = 9 - 2(5)
f(5) = -1

Maka daerah hasilnya adalah {-1,1,3,5,7,9}
