Definisi Fungsi Kuadrat
Fungsi kuadrat adalah suatu persamaan dari variabel yang mempunyai pangkat tertinggi dua.
Bentuk umum persamaan kuadrat adalah:
ax2 + bx + c = 0
Bentuk Khususnya ;
2x2 + 4x + 5 = 0
3
Langkah - Langkah Menggambar Fungsi Kuadrat
1). Tentukan titik potong dengan sumbu x (nilai y atau f(x) sama dengan 0).
2).Tentukan titik potong dengan sumbu y (nilai x = 0).
3).Menentukan sumbu simetri . (x = -b/2a)
4).Menentukan titik puncak (-b/2a, -b^2 - 4ac/4a) atau hitung nilai puncak y menggunakan substitusi/mengganti nilai x yang diperoleh pada perhitungan nomor 3 ke dalam persamaan f(x).
