Question

Sales of SUVs in the United States (in millions) for the years 1990-1999 can be modeled by the quadratic equation shown below:

y=0.016x^2 + 0.124x + 0.787

Here= 0 represents 1990, x=1 represents 1991, and so on. Use the model to approximate sales in 1994

Answer 1

In this problem they are indicating you should plug in the correct year for x. So x = 4 is 1994 and looks like this:

y=0.016(4)² + 0.124(4) + 0.787

y= 33.8192580645 Million
