18. FINANCIAL LITERACY The average annual price of crude oil can be modeled by the cubic function f(x) = 0.2728x^3- 2.612x^2+ 7.02x + 89.18, where x is the number of years after Gena began driving and f(x) is the price in dollars.
a. Graph the function for 0≤ x ≤ 10
b. Describe the turning points of the graph and its end behavior.
c. What trends in crude oil prices does the graph suggest?
d. Is it reasījnable that the trend will continue indefinitely? Explain.
