Probably the easiest way is as seen in this example:


f[x_]:=x^2


g=Plot[Evaluate[f[x],{x,1,2}],PlotPoints->5];


Cases[g,Line[x_]->x,Infinity]

{{{1.00000025, 1.0000005000000625}, {1.2434019494374948, 
1.5460484078649623}, {1.5088527991562422, 2.276636769521627},
   {1.7581561980312317, 3.0911132166756357}, {1.9979104466249689, 
3.9916461527331824}, {1.99999975, 3.9999990000000625}}}
