si el anteayer del pasado mañana de mañana del ayer del mañana de hace 2 dias es el pasado mañana del mañana del mañana del ante
ale4655 [162]

Si el día es jueves, entonces el mañana del pasado mañana de ayer de ayer es martes.

<h3>Definición del día mediante equivalencia aritmética</h3>

Sea el día <em>actual</em> (<em>lunes</em>) el día 0, el día <em>anterior</em> tiene equivalencia de -1 y el día <em>posterior</em> tiene equivalencia de +1. A continuación, traducimos matemáticamente la expresión:

<em>Si el anteayer (-2) del pasado mañana (+2) de mañana (+1) del ayer(-1) el mañana (+1) de hace 2 días (-2) es el pasado mañana (+2) del mañana (+1) del mañana (+1) del anteayer (-2) del mañana (+1) del lunes (0). ¿qué día es el mañana (+1) del pasado mañana (+2) de ayer (-1) de ayer (-1)?</em>

<h3>Simplificación</h3>

<em>Si (-1) es (+3). ¿Qué día es (+1)?</em>

Si el día es jueves, entonces el mañana del pasado mañana de ayer de ayer es martes.

stepan [7]

Answer:

- 2

Step-by-step explanation:

The composition of inverse functions gives x

g(x) and g^{-1} (x) are inverse functions, then

g^{-1} (g(x)) = x , thus

g^{-1} (g(- 2)) = - 2
