Answer 1

Respuesta:

$e = - \frac{1}{16}$

Explicación paso a paso:

Tenemos la función:

$r(x) ={x}^{2} - 4x + 1$

Entonces para hallar E debemos asignar el valor indicado en x:

$r( - 1) = {( - 1)}^{2} - 4( - 1) + 1 = 6$

$r(2) = {(2)}^{2} - 4(2) + 1 = - 3$

$r(3) = {(3)}^{2} - 4(3) + 1 = - 2$

$r(9) = {(9)}^{2} - 4(9) + 1 = 46$

Ahora calculamos el valor de E:

$e = \frac{6 + ( - 3)}{ - 2 - 46} = \frac{3}{ - 48} = - \frac{1}{16}$
