The rate of change of the weight of a mouse can be modeled as: w(t)= 7.37t-1 grams per week, where t is the age of the mouse, in weeks, beyond two weeks. At an age of 9 weeks, the mouse weighed 26 grams.
Find the Specific Antiderivative
W(t)= 7.37 ln t + 11.6586 grams
Using the graph x2, when would the graph be increasing/decreasing, and is it increasing faster or slower in these areas?
negative infinity to 0= decreasing slower
0 to infinity= increasing faster
