The accompanying graph shows how the volume of lumber V in a tree varies with time t (the age of the tree). Use the graph to estimate the rate at which V is changing with respect to time when t = 30 years. What seems to be happening to the rate of change of V as t increases without bound (that is, in the long run)?
