Consider the function as representing the value of an ounce of
palladium in U.S. dollars as a function of the
time t in days.†
R(t)
= 80 + 30t − t2; t =
5
Find the average rates of change of
R(t)
over the time intervals
[t, t + h],
where t is as indicated and
h = 1,
0.1, and 0.01 days. (Use smaller values
of h to check your estimates.) HINT [See Example
1.]
Estimate the instantaneous rate of change
of R at time t, specifying the
units of measurement.
