asta e doar un exemplu
f(-2) = -4-1= -5
f(-1) = -2-1= -3
f(0) = -1
f(1) = 2-1= 1
f(2) = 4-1= 3
f(3) = 6-1= 5
--------------------------
b.
Gf={(-2;-5), (-1;-3), (0;-1), (1;1), (2;3), (3;5)}
-----------------------------------------------------------------
c.
Imf=multimea valorilor functiei sau numita si codomeniul = {-5,-3,-1,1,3,5}
---------------------------------------------
succes
