  • 27. Kaedah Jadual vs Kaedah Maths Lakar Graf Kebaikan Kaedah Jadual 1. Graf yang dilakar selalunya betul 2. Kaedah permulaan yang cepat Kaedah Matematik 1. Hanya perlu 3 titik koordinat kelemahan 1. Banyak titik koordinat perlu dicari 1. Tidak selalunya betul kerana melibatkan kiraan matematik 2. Kaedah permulaan lambat kerana perlu ingatan formula Kesimpulan 1. Power Lukisan 1. Power Matematik Chin Seng Fatt Melakar Graf Fungsi Kuadratik 27
