Răspuns :
f(x)-3supra 2 ori x+1 pe 2
=3x+3
x=3supra3
x=1
f(-1)=3*(-1)+3=-3+3=0
f(0)=3*0+3=0
f(2)=3*2+3=6+3=9
f(3)=3*3+3=12
(*=ori)
=3x+3
x=3supra3
x=1
f(-1)=3*(-1)+3=-3+3=0
f(0)=3*0+3=0
f(2)=3*2+3=6+3=9
f(3)=3*3+3=12
(*=ori)
deci inlocuiesti x cu nr de la f() si ai rezultatele
f(-1)=0
f(0)=3/4
f(2)=9/4
f(3)=3
f(-1)=0
f(0)=3/4
f(2)=9/4
f(3)=3
