式の形を覚えることも大事だけど、「なぜ、そうなるのか？」を考えることも大事です。また、グラフをイメージし、頭の中で、式とグラフを結びつける練習をしましょう。簡単な問題から少しずつステップアップして解いてみたりして、徐々に理解できるように！ 焦らず、一つずつ確実に進めよう！

Remembering the form of the equation is important, but it's also crucial to think about "why it works that way." Also, practice visualizing the graph and connecting the equation to the graph in your mind. Start with simple problems and gradually work your way up to more difficult ones, so you can understand it step by step! Don't rush; just make steady progress one step at a time!
