Решить 3 и 5 задание

Answer 1

3) f(x) = (x+1)^3 при x=-1: f(-1) = (-1+1)^3 = 0^3 = 0; f(1) = (1+1)^3 = 8

5) 1)  1/(x-1) - x при x=0: 1/(0-1) - 0 = 1/1 - 0 = 1.

1/(-1-1)-(-1) = 1/(-2) + 1 = -1/2 + 1 = 1/2

1/(0.2-1) - 0.2 = 1/(-0.8) - 0.2 = -1.25 - 0.2 = -1.45

2) g(0) = sqrt(5*0-0^2) = 0

g(1) = sqrt(5*1-1^2) = sqrt(4) = 2

g(3) = sqrt(5*3-3^2) = sqrt(15-9) = sqrt(6)
