1) Уравнение прямой с отрицательным угловым коэффициентом. Значит, максимальное значение принимает в начале отрезка, а минимальное в конце. Таким образом, g(0) = Gmax = 3; g(3) = Gmin = -3.

4)
g(x) = 2x - 4x = -2x. Прямая с отрицательным угловым коэффициентом. Максимум в точке 1, минимум в точке 3.
Gmin = -6, Gmax = -2
