Hello, my friend! Finally I get time to write you! How are you doing? It's going to be my birthday in 4 days and I want you to know that it's my favorite Holliday! It's a special day for me and I celebrate it every year! I have a small tradition. Every birthday morning my parents wake me up and present me my birthday gift and cake! After this I decorate the house and prepare everything to the birthday party. My mom cooks special dishes. In the evening all my relatives come to my house! All of them congratulate me and give me gifts! This is my favorite part! We have fun and take photos together! In the weekend I celebrate my birthday with my friends! Every year we do it in different place so it's always so interesting and unforgettable! I'm looking forward for my birthday!

1) Координата Y у точки A - 2. Подставляем в уравнение графика:
Координата X у точки A равна 2. Подставляем в уравнение:
Равенство не является верным, сл-но точка А не принадлежит графику y = x^2
2) Координата Y у точки B равна 1. Подставляем в уравнение графика:
Координата X у точки B равна 1. Подставляем в уравнение:
Равенство является верным, сл-но точка B принадлежит графику y = x^2
3) Координата Y у точки C равна -3. Подставляем в уравнение графика:
Координата X у точки C равна -3. Подставляем в уравнение:
Равенство не является верным, сл-но точка C не принадлежит графику y = x^2
4) Координата Y у точки D равна -4. Подставляем в уравнение графика:
