5. SPRINGS When a weight up to 15 pounds is attached to a 4-inch spring, the length 2, in inches, that the spring stretches is represented by the function L(w) =
=;w + 4, where w is the weight, in
pounds, of the object. State the domain and range of the function. Then determine whether it is
one-to-one, onto, both, or neither and whether it is discrete, continuous, or neither discrete nor
continuous
