Question

si P(x+3)= x+2. Calcular P(x)

Answer 1

P(X) = x+2-3
P(x) = x-1

Answer 2

Se desarrolla así:

Primero calculamos "x":

                                          x + 3 = x

                                             x    = x - 3

Reemplazamos:

                               P(x) = ( x - 3 ) + 2

                                  P(x) =  x - 1
