\n" ); document.write( "\n" ); document.write( "Notice that the differences in log base 10 for Y are nearly all the same, 0.11. This means \"log%2810%2CY%29\" is a linear function of time x in hours. You could choose as a vertical axis intercept, (0, 2.70). The goal is to finally get an exponential function but you can start with the linear form of it.\r
