Although the playing surface of a football or soccer field appears to be flat, its surface is actually shaped like a parabola so that rain runs off to either side. The cross section of a field with synthetic turf 2. can be modeled by f(x)=-0.000234(x -80)+1.5 where x and y are measured.in feet. A. Find the width of the field. B. What is the maximum height.of the field?. C. Explain how the width and height relate to domain and range.
