I have some data, but I can’t seem to figure out the function eqation that matches the data.  
There are 2 variables, R and D.  
here is a chart:  
R | D

* * *

5 | 50  
15 | 50  
45 | 45  
50 | 41

so in other words, when R is 5 then D is 50. But… given that data I can’t figure out the equation f®=D.

Just if your’e wondering, this is for a flash game I am making; it has to do with the \_rotation of something and the y velocity of something else…
