Question

1. Evalúa la funcion f(x) = 2x2 - 1 en los puntos X=-2 ,X = -1X = 0 ,X = 1YX = 2.​

Answer 1

Explicación paso a paso:

$f(x) = 2 {x}^{2} - 1$

$f( - 2) = 2( - 2)^{2} - 1 = 7$

$f( - 1) = 2( - 1)^{2} - 1 = 1$

$f(0) = 2(0)^{2} - 1 = - 1$

$f(1) = 2(1)^{2} - 1 = 1$

$f(2) = 2(2) ^{2} - 1 = 7$
