Question

el polinomio P(x + 2) = 2x -5
calcula P(-2)

Answer 1

Hola! :3

Problema 1:

Igualamos:

P(x + 2) = P(-2)

x + 2 = -2

x = -2 - 2

x = -4

Reemplazamos:

P(-2) = 2(-4) - 5

P(-2) = -8 - 5

P(-2) = -13

Problema 2:

Igualamos:

P(x) = P(2)

x = 2

Reemplazamos:

P(2) = 2(2)² + 3(2) - 1

P(2) = 2(4) + 6 - 1

P(2) = 8 + 6 - 1

P(2) = 14 - 1

P(2) = 13

Espero haberte ayudado :D
