  1. FUNGSI KUADRAT SRI SULASMIYATI, S.SOS, M.AP

  2. FUNGSI KUADRAT • Persamaan Umum y = ax2 + bx + c Untuk melukiskan fungsi kuadrat diperlukan : • Apabila x = 0 maka y = .... • Apabila y = 0 maka x = ...(difaktorkan atau dengan rumus ABC) • Titik puncak dimana dan Dimana D = b2 – 4ac 4. Sumbu simetri

  3. MACAM – MACAM PARABOLA

  4. x = ay2 + by + c • Koordinat titik puncak

  5. Contoh : y = x2 – 8x + 15 • Apabila x = 0 maka y = 15 (0,15) • Apabila y = 0 maka (x – 5)(x – 3) = 0 x1 = 5 (5,0) x2 = 3 (3,0) c. Titik puncak , P (4, -1) d. Sumbu simetri x = = 4

  6. Contoh : x = y2 – y – 6 • Koordinat titik puncak = • Untuk y = 0 maka x = -6. Maka titik potong dengan sumbu x = (-6,0) • Untuk x = 0 maka y2 – y – 6 = 0. memakai rumus ABC y1 = 3 (0,3) dan y2 = -2 (0,-2)
