Question 760907: A rectangular area of 2,000 square feet is to be fenced on three sides with fence costing $0.30 per foot and on the fourth side with fence costing $0.50 per foot. If x denotes the length of the fourth side and C = f(x) denotes the corresponding cost of the fence in cents. Give the domain of the function.
Answer by KMST(5328)   (Show Source):
You can put this solution on YOUR website! The only constraint given is that the area fenced should be 2000 square feet.
If this is not supposed to be realistic, x could be any positive real number.
So the domain would be all the positive real numbers.
It could be x=2000 feet, and then you would be fencing an area 1 foot by 2000 feet.
We could make x=20,000 feet long and the fenced area width would be 0.1 foot=1.2 inches.
As the width gets more ridiculously small, x could get as large as we want.
