Tolong dijawab ya yg no. a. Makasih

i) Domain = {1,2,3,4,5,6}
Kodomain =
f(1) = 1-1 = 0
f(2) = 2-1 = 1
f(3) = 3-1 = 2
f(4) = 4-1 = 3
f(5) = 5-1 = 4
f(6) = 6-1 = 5
Kodomain = {0,1,2,3,4,5}

ii) Domain = {1,2,3,4,5,6}
Kodomain =
f(1) = 1+3 = 4
f(2) = 2+3 = 5
f(3) = 3+3 = 6
f(4) = 4+3 = 7
f(5) = 5+3 = 8
f(6) = 6+3 = 9
Kodomain = {4,5,6,7,8,9}

Tabelnya tinggal digambar aja ya...
Semoga dapat membantu
