Первая производная функции y:y' = 2(-2x^2 + x + 2)(-4x + 1)
Вторая производная функции y:y'' = 2(-4x + 1)(-4x + 1) + 2(-2x^2 + x + 2)(-4)
Подставляем x = 1:y''(1) = 2(-41 + 1)(-41 + 1) + 2(-2*1^2 + 1 + 2)(-4)y''(1) = 2(-3)(-3) + 2(-2 + 1 + 2)(-4)y''(1) = 2(9) + 2(1)(-4)y''(1) = 18 - 8y''(1) = 10
Итак, y''(1) = 10.
