Jika grafik fungsi kuadrat FX = -1/2x^2 – 4x -6 digeser ke kanan 5 satuan grafik hasil penggeseran akan memotong sumbu y dititik….

#F

f(x)= -1/2 x²  - 4x – 6

digeser 5 satuan ke kanan

f(x) = – 1/2 (x – 5)² – 4(x – 5) – 6

f(x) = – 1/2 (x² -10x + 25) – 4x+ 20 – 6

f(x) = -1/2 x²+ 5x – 25/2  - 4x+ 14

f(x) = – 1/2 x² + x  + 3/2

titik potong sumbu y , jika  x = 0

f(0) = -1/2 .0² + 0 + 3/2

f(0) = 3/2

titik potong (x, f(x)) = (0, 3/2)
