РЕШЕНИЕ
а) Y = 1/2*(x-1)² + 3 = 1/2*(x² - 2x + 1) + 3 = x²/2 - x + 3.5
ОТВЕТ: a = 1/2, b= - 1, c= 3.5
б) Y = 1/2*(x² - 2) - 2 = 1/2*(x² - 4x + 4) - 2 = x²/2 - 2x
ОТВЕТ: a = 1/2, b = - 2, c = 0.
в) Y = 1/2*(x² + 5) -1 = 1/2*(x² + 10*x + 25) - 1 = x²/2 + 5x + 11.5
ОТВЕТ: a = 1/2, b = 5, c = 11.5
г) Y = 1/2*(x² + 1.1) - 1.1 = 1/2*(x² +2.2*x + 1.21) - 1.1 = x²/2 + 1.1*x - 0.495
ОТВЕТ: a = 1/2, b = 1.1, c = - 0.495
