Question

g(x) = x³ - 3x² + 5x - 7 calcular el valor de g(-2) + g(2)

Answer 1

g(2) = 2³ - 3(2)² + 5(2) - 7
g(2) = 8 - 3(4) + 10 - 7
g(2) = 8 - 12 + 10 - 7
g(2) = -4 + 3
g(2) = -1

g(-2) = (-2)³ - 3(-2)² + 5(-2) - 7
g(-2) = -8 - 3(4) - 10 - 7
g(-2) = -8 - 12 - 10 - 7
g(-2) = -37

Por lo tanto, g(-2)+g(2) = -1 + -37 = -38

Espero te sirva, saludos!

Answer 2

G(2) = (2)³ - 3(2)² + 5(2) -7

G(2) = 8 - 3(4) + 10 - 7

G(2) = 8 - 12 + 10 - 7

G(2) = 18 - 19

G(2) = -1

G(-2) = (-2)³ - 3(-2)² + 5(-2) -7

G(-2) =  - 8 - 12 - 10 - 7

G(-2) = -37

Ahora: G(-2) + G(2)

-1 + (-37) = -38
