Modeling Energy from crude oil The table shows the total energy supply from crude oil products, in quadrillion BTUs, for selected years from 2010 and projected to 2040.

(a) Find the cubic function that is the best model for the data. Use x as the number of years after 2010 and C(x) as the quadrillion BTUs of energy from crude oil products. Report the model with three significant digit coefficients.

(b) Find the critical values of the reported model.

(c) Find the reported model’s critical points and classify them.

(d) Do you think this model will be valid for years past 2040? Explain.

(a)

To determine

The cubic function that best models the size of this data, where x is the number of years after 2010, if the following table shows the total energy supply from crude oil products, in quadrillion BTUs, for selected years from 2010 to 2040.

Year BTU Year BTU
2010 11.6 2030 13.5
2015 15.6 2035 13.4
2020 16.0 2040 13.1
2025 14.5
Explanation

Given Information:

The provided table is:

Year BTU Year BTU
2010 11.6 2030 13.5
2015 15.6 2035 13.4
2020 16.0 2040 13.1
2025 14.5

Explanation:

The critical values are the only values at which the graph can have turning points, the derivative cannot change sign anywhere except at the critical value.

This, in an interval between two critical values, the sign of the derivative at any value in the interval will be the sign of the derivative at all values in the interval...

(b)

To determine

To calculate: The critical values of the data if the following table shows the total energy supply from crude oil products, in quadrillion BTUs, for selected years from 2010 to 2040.

Year BTU Year BTU
2010 11.6 2030 13.5
2015 15.6 2035 13.4
2020 16.0 2040 13.1
2025 14.5

(c)

To determine

To calculate: The critical points of the data and also classify them, if the following table shows the total energy supply from crude oil products, in quadrillion BTUs, for selected years from 2010 to 2040.

Year BTU Year BTU
2010 11.6 2030 13.5
2015 15.6 2035 13.4
2020 16.0 2040 13.1
2025 14.5

(d)

To determine

If this model will be valid till 2040 if the following table shows the total energy supply from crude oil products, in quadrillion BTUs, for selected years from 2010 to 2040.

Year BTU Year BTU
2010 11.6 2030 13.5
2015 15.6 2035 13.4
