F(x) = 2x+1/×-1 find the inverse function
denis23 [38]
To factor this, start by replacing x with y and then solve for y
f(x) = \frac{2x+1}{x - 1}
x = \frac{2y+1}{y - 1}
(y-1)x = \frac{2y+1}{y - 1} * (y-1)
(y-1)x = 2y+1
xy -x = 2y+1
xy - 2y -x +x = 2y - 2y +x+1
xy - 2y = x+1
Factor out y on the left side. 
\frac{xy - 2y}{y} = x+1
y(x - 2) = x+1
\frac{y(x - 2)}{(x-2)} = \frac{x+1}{x-2}
y = \frac{x+1}{x-2}
f(x)^{-1} = \frac{x+1}{x-2}

Supongamos que estás en el infierno y el diablo te reta a un juego. Él piensa en un número natural.Cada día, tú tendrás una opor
Blababa [14]

Answer:

En síntesis, se inicia con el número natural más pequeño en el primer y se prosigue con los números siguientes en caso de no dar con n, de modo que el participante pasará en el infierno únicamente n días, algo pequeño en comparación con la eternidad.

Step-by-step explanation:

Los números naturales comprenden el subconjunto más pequeño de los números reales conformado por los siguientes elementos:

\mathbb{N} = \{1,2,3,4,...\}

Sea n \in \mathbb{N} el número que tiene el diablo en su mente, tal que n \geq 1. Comenzamos el primer día con 1, si este no corresponde con n. Entonces se utiliza 2 al día siguiente y este no corresponde, se emplea al día siguiente y así sucesivamente hasta conseguir n.

En síntesis, se inicia con el número natural más pequeño en el primer y se prosigue con los números siguientes en caso de no dar con n, de modo que el participante pasará en el infierno únicamente n días, algo pequeño en comparación con la eternidad.
