Dketahui F (x)= 3x-6 dngan domainnya {-1,0,1,2,3,4}

Kodomain:
f(-1) = 3(-1)-6 = -3-6 = -9
f(0) = 3(0)-6 = 0-6 = -6
f(1) = 3(1)-6 = 3-6 = -3
f(2) = 3(2)-6 = 6-6 = 0
f(3) = 3(3)-6 = 9-6 = 3
f(4) = 3(4)-6 = 12-6 = 6

Jadi, kodomain/daerah kawannya adalah {-9,-6,-3,0,3,6}

Semoga dapat membantu~

F(-1) = 3.-1-6
=-3-6
= -9

F(0)= 3.0-6
=0-6
=-6

F(1)=3.1-6
=3-6
=-3

F(2)=3.2-6
=6-6
=0

F(3)=3.3-6
=9-6
=3

F(4)=3.4-6
=12-6
=6
