Play with the given equation until you can make a variable substitution which will get it into the form of a straight line. Then plot the data, which should plot as a straight line. Fit the data by making a call to polyfit, using 1 as the last argument. Find a and b. Finally, check your values of a and b by plotting the function on top of the data.
24. Growth data of a sunflower plant is given in the following table: 7 21 35 49 63 77 8.5 21 50 77 89 98 Day Height (in.) 91 99
8.6 The data can be modeled with a function in the form y=_H where y 1+e (a+b), t is the height, H is a maximum height, a and b are constants, and is the number of days. By using the method described in Section 8.2.2, and assum- ing that H = 102 in., determine the constants a and b such that the function best fits the data. Use the function to estimate the height in day 40. In one figure, plot the function and the data points. 25. Use the growth data from Problem 291
