If you do the graph, you'll see that it turns downward at t = 1.85, then turns back up at t=4.25
So, consumption of oranges increased until about November of 1992, then decreased through March of 1995, when it started to increase again.
Don't know what happened during those three years; drought? freeze? disease? check elsewhere for that info.
the average amount of oranges in pounds eaten per person each year in the 6 can be modeled byunited states from 1991 to 1996 by
0.298x^3-2.73x^2+7.05x+8.45
where x is the number of years since 1991. Graph the function and identify any turning points on the interval 0<x<5. What real life meaning do these points have?
