1) y = 7 + 12x - x^3
x1 = -2
y = 7 - 12*2 + 2^3 = 7 - 24 + 8= -9
x2 = -1
y = 7 - 12 + 1 = 8 - 12 = -4
x3 = 0
y = 7 + 12*0 - 0 = 7
x4 = 1
y = 7 + 12 - 1 = 19 - 1 = 18
x5 = 2
y = 7 + 12*2 - 2^3 = 7 + 24 - 8 = 24 - 1 = 23
Ответ у = 23
2) y = (x - 8) * c^(x - 7)
x1 = 6
y = (6 - 8) * c^(6 - 7) = -2/c^2
x2 = 7
y = (7 - 8)*c^(7 - 7) = -1*1 = -1
x3 = 8
y = (8 - 8)*c(8 - 7) = 0
