Question

Si:
P(x+2)=6x+1,
P(F(x))=12x-1. Halle F(10)

Answer 1

P(x+2) = 6x + 1

x ----> x - 2

------------------

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

  P(x)   = 6x - 12 + 1

  P(x)  = 6x - 11

P(F(x)) = 6F(x) - 11

-----------------------------

P(F(x)) = 12x - 1

6F(x) - 11  = 12x - 1

6F(x)    = 12x - 1 + 11

6F(x)   = 12x + 10

 F(x)  = (12x + 10)/6

Nos piden F(10)

F(x) = (12x + 10)/6

F(10) = (12(10) + 10)/6

F(10) = (120 + 10)/6

F(10) = 130/6

F(10) =65/3 >>>Respuesta

----------------------------------

eso es todo :D

SALUDOS!!
