g(-1) = -1, g(2) + g(1) = 7
Step-by-step explanation:
Given: g(x) = x³ + x² - x - 2
g(-1) ==> x = -1
g(-1) = (-1)³ + (-1)² - (-1) - 2
g(-1) = -1 + 1 + 1 - 2
g(-1) = -1
g(2) ==> x = 2
g(2) = (2)³ + (2)² - (2) - 2
g(2) = 8 + 4 - 2 - 2
g(2) = 8
g(1) ==> x = 1
g(1) = (1)³ + (1)² - (1) - 2
g(1) = 1 + 1 - 1 - 2
g(1) = -1
g(2) + g(1) = 8 + (-1) = 7
