It is not clear how you want f3 handled for x<0

Needs["Graphics`"];

f3[x_ /; x==0] = 1;
f3[x_] := Abs[Sin[x]/x];

Plot[f3[x], {x, 0, 3Pi},
    PlotStyle -> Blue,
    Ticks -> {PiScale, Automatic},
    PlotRange -> All,
     Epilog ->
      {AbsolutePointSize[6], Red, 
        Point[{0, f3[0]}]}];

f3 := Which[x==0,1,0<x,Abs[Sin[x]/x]];

F3 ist defined on x=0 (analytische Fortsetzung).
How can I force mathematica to plot the graph on x=0?
