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

f(x) = 9 - 2x
domain = {0,1,2,3,4,5}
kodomain ={...}

f(0) = 9 - 2(0) = 9 - 0 = 9
f(1) = 9 - 2(1) = 9 - 2 = 7
f(2) = 9 - 2(2) = 9 - 4 = 5
f(3) = 9 - 2(3) = 9 - 6 = 3
f(4) = 9 - 2(4) = 9 - 8 = 1
f(5) = 9 - 2(5) = 9 - 10 = -1

kodomain ={9,7,5,3,1,-1}
