помогите решить N193 (всё кроме а,г)

б) g(-2) = (-2)²/3 = 4/3 
g(0) = 0
g(1/2) = (1/2)²/3 = 1/12
g(2) = (2)²/3 = 4/3
в) g(-2) = 1 - (-2)² = 1-4 = -3
g(0) = 1-0 = 1
g(1/2) = 1 - (1/2)² = 1-1/4 = 3/4
g(2) = 1 - (2)² = 1-4 = -3
д) g(-2) = -(-2)³ = -(-8) = 8
g(0) = 0
g(1/2) = -(1/2)³ = -1/8
g(2) = -(2)³ = -8
e) g(-2) = ((-2)³/2) - 1 = -4-1 = -5
g(0) = 0-1 = -1
g(1/2) = ((1/2)³/2) - 1 = 1/16 - 1 = -15/16
g(2) = ((2)³/2) - 1 = 4-1 = 3
