## Intermediate Algebra (6th Edition)

We know that the number of barrels is modeled by: $y=-10x^2+193x+8464$ Where x is in years and y is in thousands of barrels per day. To find the value in 2004, we plug in 4: $y=-10(4)^2+193(4)+8464$ $y=9,076,000 barrels$ (We multiplied by 1000 since the answer is in thousands).
