Uuuuuhhhhh...... what is the scale? I can tell you that you subract the number x by the numerator (the two) and the number y by the denominator (the three)
<h2><u><em>at x = 3 D = .1086</em></u></h2><h2><u><em /></u></h2><h2><u><em>at x = 4 D = .0869</em></u></h2><h2><u><em /></u></h2><h2><u><em>at x = 5 D = .0724</em></u></h2>
