Please help me in solving this problem.
Test
The U.S. Crude Oil production, in billions of barrels, for the years from 2005 projected to 2025, can be modeled y = -0.003x2 +0.028x +1.991. with x equal to the vears after 2005 and y equal to the number of billions of barrels of crude oil.
a. Find and interpret the vertex of the graph of this model.
b. What does the model predict the crude oil production will be in 2028?
c. Graph the function for the years 2005 to 2025,
a. The vertex of the graph of this model isv=( ). (Round to three decimal places as needed)
