Объяснение:
f(t)=t² - 1/4 · t - 9, при t=4 f(t)= 4²- 1/4· 4 - 9 =16-1-9=6 , значит координаты искомой точки (4; 6) 2)
Дана Парабола y=x^2 напишите уравнение каждый из полученных при следующих сдвигах данные параболы:

3)на 7 единиц вправо вдоль оси Ox у = (х-7)²
4)на четыре единицы влево вдоль оси Ox у= (х+4)²
5)на 9 дней?? цифра вдоль оси Ox и на 6 единиц вверх вдоль оси Oy??? у=(х-9)²+6
am Andrew Kiporuk. I am a puple of the 10th form. I get ut ap 7 o'clock. I wash myself and dress.I make a bed. My friend come to me at half past 7 and we go to the school. At school I have 7 lessons.
