I'm trying to find a common formula for all the curves found in the attached chart. Is this possible at all
For instance, I have the first line, let's ignore the scale of the chart and use it as a grid, it has the following points:
- P1 = x = 0 y = 90
- P2 = x = 10 y = 102
- P3 = x = 20 y = 112
- P4 = x = 30 y = 119.5
- P5 = x = 40 y = 124.5
- P6 = x = 50 y = 128.5
- P7 = x = 60 y = 130.5
- P8 = x = 65 y = 131
Then there's another line, further up the chart, with the following points:
- P1 = x = 0 y = 160
- P2 = x = 10 y = 176
- P2 = x = 10 y = 102
- P3 = x = 20 y = 189.5
- P4 = x = 30 y = 199.5
- P5 = x = 40 y = 207
- P6 = x = 50 y = 212
- P7 = x = 60 y = 215
- P8 = x = 65 y = 215.5
Is it possible to find the formula and apply it anywhere on the chart? I would appreciate your guidance and patience as I'm coming from a humanities education.
