Log function fit
Witryna28 paź 2013 · f ( x) = l o g ( a x + 10) + 4. We have f ( 180) = 9, so. f ( 180) = l o g ( 180 a + 10) + 4 = 9. that is, l o g ( 180 a + 10) = 5. a = ( 10 5 − 10) / 180. hence f ( x) is (you can do the required simplification if you want to...): f ( x) = l o g ( ( 10 5 − 10) / 180) x + 10) + 4. Needless to say that there may be other functions that could ... WitrynaFinding the function from the log–log plot.
