Bacterial growth can be exponential. Let X = time in hours & Y = the number of bacteria. Using Excel and the Trendline function, answer the following questions by fitting an exponential equation to the following data (X,Y): (1,4.84), (1.5,4.78), (3,23.22), (5,130.02), (8,422.93). Change the appropriate axis to a logarithmic scale. The exponential equation is Y = a e(bx), where e is the base of the natural logarithm. e(bx) can also be written EXP(bx).
