Drawing a given mathmatical function ?

hi all 

I have a very accurate curve to draw using coreldraw in order to use it with CNC machine ..

the curve is represent the function   y=x^2 * 0.0017361   which  x varies from 0  to 120   y relativly varies from 0 to 25 

how can I do it  ?  I used many function plotter and imported it into Coreldraw but it was with low resolution  some suggest to draw it handly using ( 3 point curve tool ) but it will reduce the accuracy of curve with much waste of time and concentration .

hope to hear sufficient solutions
