(b) The cubic function of best fit to these data is
H(x) = 0.159x° - 2.320x2 + 9.330x - 4.2142.
Use a graphing utility to verify that this is the cubic function of best fit. Use this function to predict the number of major
hurricanes that struck between 1961-1970.

(d) Concern has risen about the increase in the number and intensity of hurricanes, but some scientists believe this is
just a natural fluctuation that could last another decade or two. Use your model to predict the number of major
hurricanes that will strike between 2001 and 2010.
