Question

c) Estimate the instantaneous rate of growth in 2006 by measuring the slope of the tangent line through
(2005, 10237) and (2007, 15005).

d) Estimate the instantaneous rate of growth in 2007 by measuring the slope of the tangent line through
(2006, 12435) and (2008, 16684).


e)Compare the growth rates you obtained in part (c) and (d). What can you conclude?

Answer 1

(c) (15005-10237)/2 = 2384
(d) (16684-12435)/2 = 2124.5
(e) Looks like growth is slowing down

Answer 2

Slope of 2005 and 2007
