The width w in centimeters of a tortoise can be modeled by the function
w = 119 - 77e-0.178t where t is the tortoises age in years. Graph this model and use the graph to estimate the width of a tortoise that is 3 years old. Round your answer to the nearest whole centimeter.
Width = cm
The trace feature on the graph tells us that when t = 3, w ≈ 74cm.
