Crude Oil The following table gives the U.S. crude oil production, in billions of barrels, for the years from 2010 projected to 2030.
a. Graph a
b. Find the power function that models the data, with x equal to the number of years after 2000 and y equal to the number of billions of barrels of crude oil.
c. Find the quadratic function that models the data, with x equal to the number of years after 2000 and y equal to the number of billions of barre crude oil.
d. Use the power model to predict the number of billions of barrels of crude oil in 2040.
e. Use the quadratic model to predict the number of billions of barrels of crude oil in 2040.
f. If the crude oil production begins to decrease after 2030, which model is the better fit for data?

(f) Create an equation of this form that has 7 as a solution and an extraneous solution. Give the extraneous solution. (g) What must be true about the value of bx + c to ensure that there is a real number solution to the equation? Explain.arrow_forward
- The equation ×+ 2 = √3x+10 is of the form ×+ a = √bx + c, where a, b, and c are all positive integers and b > 1. Using this equation as a model, create your own equation that has extraneous solutions. (d) Using trial and error with numbers for a, b, and c, create an equation of the form x + a = √bx + c, where a, b, and c are all positive integers and b>1 such that 7 is a solution and there is an extraneous solution. (Hint: Substitute 7 for x, and choose a value for a. Then square both sides so you can choose a, b, and c that will make the equation true.) (e) Solve the equation you created in Part 2a.arrow_forwardA basketball player made 12 out of 15 free throws she attempted.
