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) = 240 + 40t - t3; t = 2

Find the average rate 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

Then there is a table setup like this:

h 1 0.1 .01
ave rate ?

Solving for the question marks

Hence, estimate the instantaneous rate of change of R at time t, specifying the units of measurement.

2.8×10^ -5
Scientific notation is found by finding a number between 1 up to 9.9 (but not 10).

eg. 2.8 ( place à dot in between the number and count back to the original dot)
0.00002.8 (it moves 5 times)
Use ×10 to indicate the position (No of 0's)
if you move to the left, the power is -
If you move to the right, the power is +

Therefore 2.8×10^-5
