Jika f(x) = x + 3 dan (g o f)(x) = 2x² + 4x – 3, maka (f o g)(1)= … 28/07/2022 by hadi wargamasyarakat Jawab: g o f(x) = (g.(x + 3)) 2x² + 4x – 3 = 2(x + 3)² – 8(x + 3) + 3 g(x) = 2x² – 8x + 3 f o g(x) = 2x² – 8x + 3 + 3 f o g(x) = 2(1)² – 8(1) + 6 = 0 Persamaan garis singgung elips 16x² + 9y² + 64x - 54y + 1 = 0 sejajar garis x - y + 4 = 0
