I get 6220
That 6200 is unlikely, since the first two terms don't ad to zero...
The equation y=−0.065x2+6.875x+6200 models the amount y of sugar (in pounds per square foot) produced where x is the amount of fertilizer (in pounds per square foot) used.
What is the best approximate for the amount of sugar produced when 3 pounds per square foot of fertilizer is used?
