Estamos ante una funcion a trozos
Entonces :
Calcular : F(F(-2)) + F(F(4))
Para x = -2 ; F(x) = x+1
F(-2) = -2 + 1
F(-2) = -1
Para x = 4 ; F(x) = x-1
F(4) = 4 - 1
F(4) = 3
-----------------------
Calcular
F(F(-2)) + F(F(4))
F(-1) + F(3)
-----------------
Para x = -1 ; F(x) = x+1
F(-1) = -1 + 1
F(-1) = 0
Para x = 3 ; F(x) = x-1
F(3) = 3 - 1
F(3) = 2
-------------------
Calcular.
0 + 2 = 2 >>> Respuesta
