h(1) = 2.1-1 =1
h(2) = 2.2-1=3
h(3) = 2.3-1 = 5
h(4) = 2.4-1 = 7
pasangan berurutan = {(1,1).(2,3),(3,5).(4,7)}
Grafik:
digambar aja grafik, buat titik di garis x=1, y=1. Terus di x=2, y=3, di x=3, y=5, di x=4, y=7 terus dihubungin titiknya jadi sebuah garis
Tabel :
buat f(x) sama x nya urutin aja pake pasangan berurutan
Diagram panah:
buat domain = {1,2,3,4}, terus kodomain {1,3,5,7} terus dihubungin (1 sama 1, 2 sama 3, 3 sama 5, 4 sama 7)
a) h(1) = 2(1) - 1 = 1
h(2) = 2(2) - 1 = 3
h(3) = 2(3) - 1 = 5
h(4) = 2(4) - 1 = 7
dst
pasangan berurutan: {(1,1),(2,3),(3,5),(4,7),...}
b) Domain Kodomain
1 → 1
2 → 3
3 → 5
4 → 7
c) tabel:
domain | kodomain/range
1 1
2 3
3 5
4 7
