Pt a avea limite in punctul xo=1 pui conditia ca limitele laterale sa fie egale
Ls x→1 x<1 lim f(x)=lim(2x²+3)=2*1²+3=2+3=5
Ld x→1 x>1 limf(x) =lim(5x-1)=5*1-1=4
4≠5 Ls=Ld=.> functia nu are limita in xo=1
cazul xo=2
Ls x→2 x<2 lim f(x)= lim(5x-1)=5*2-1=9
Ld x→2 x>2 limf(x)=lim(5x-1)=5*2-1=9
Ls=Ld=9 functia are limita in x=2
