Penjelasan dengan langkah-langkah:
1. Cari titik potong dengan sumbu x : y = 0
[tex]y = {x}^{2} + 2x + 1 \\ 0 = {x}^{2} + 2x + 1 \\ 0 = {(x + 1) \\ }^{2} \\ {(x + 1)}^{2} = 0 \\ x + 1 = 0 \\ x = - 1[/tex]
Koordinator titik potong: (-1, 0).
2. Cari titik potong dengan sumbu y: x = 0
[tex]y = {x}^{2} + 2x + 1 \: \: \\ \: \: \: \: \: \: = {0}^{2} + 2 \cdot \: 0 + 1 \\ = 0 + 0 + 1 \\ = 1 \: \: \: \: \: \: \: \: \: \: \: \: \: \: [/tex]
Koordinator titik potong: (0, 1).
