adjacent to the enclosure is 130 ft long and a portion of this side is used as the fourth side of the enclosure. Let x and y be the dimensions of the enclosure, where x is measured parallel to the building, and let L be the length of fencing required for those dimensions. (a) Find a formula for L in terms of x and y. L(x, y) = = (b) Find a formula that expresses L as a function of x alone. L(x) = (c) What is the domain of the function in part (b)? Express as an interval. Domain =
