Answer:
Step-by-step explanation:
x^2 + 2x - 3 = (1)^2 + 2(1) - 3 = 0 for x = 1
(2)^2 + 2(2) - 3 = 5 for x = 2
(3)^2 + 2(3) - 3 = 12 for x = 3
x^3 + 5 = (1)^3 + 5 = 6 for x = 1
(2)^3 + 5 = 13 for x = 2
(3)^3 + 5 = 32 for x = 3
x^2 + 5x + 4 = (1 )^2 + 5(1) + 4 = 10 for x = 1
(2)^2 + 5(2) + 4 = 18 for x = 2
(3)^3 + 5(3) + 4 = 46 for x = 3
