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 can be modeled by f(x) = -0.000234(x - 80)^2 + 1.5 where x and y are measured in feet.
Width = 160.064 feet wide
Height = 1.5 feet
how does the width and height relate to domain and range?
1 answer
The domain and range can only be real life values, so the function can not have negative numbers in the solution of the sketch. Only the positive values would be measurements for a football field.
