These data can be modeled with the function

*E(t)* is the energy use per dollar of GDP (indexed to 1980) and *t* is the number of years past 1980.

(a) Find *E'*(*t*).

(b) Use this model to find and interpret the instantaneous rates of change of energy use per dollar of GDP in 2000 and 2025.

(c) Use the data in the table to find an average rate of change that approximates the 2025 instantaneous rate.
