Автор ответа: Аноним

F(x)=x²-5x+6=(x²-5x+6,25)-6,25+6=(x-2,5)²-0,25
Это парабола у=х² с вершиной в точке (2,5;-0,25),область определения которой (-∞;∞),а значит она непрерывна

УМОЛЯЮ ПОМОГИТЕ С ПЕРЕВОДОМ ПОЖАЛУЙСТА!!!!!!! ПРОШУ !!!!

As Marley begins to adjust to his new home, John and Jenny have to adjust to the new fur ball trouble maker that is running rapid in their house. In just a few days of living their Marley found out one thing, that he loved toilet paper, and he loved running around the house with it eve more. He also loved to eat, and he ate everything in sight. He was also house broken within a few weeks of living with John and Jenny.

One thing Marley could do really well was grow, he grew leaps and bounds each day, and as time went on John and Jenny had officially puppy proofed the house. They moved anything that was below knee high to a different place for fear of it being knocked over by Marley's tail. Jenny's favorite nickname for Marley was Mr. Wiggles. As he was getting older he was still getting ore energetic, wanting to run and frolic wherever he could. When he would be walked in the morning, it was more of a run, so much so that only John could hold on to him when they ran. Jenny on the other hand, no matter how hard she tried she could not hold onto Marley's leash. however their was one thing that she was good at. It was taking care of Marley.

One day after a doggy playmate left they began to notice a strange behavior that they had never seen. Marley was doing everything he could to scratch everywhere. Jenny began going through his fur and discovered fleas. She was a protective mother and she wasn't about to let flees invade her home and her fur ball puppy.
