Writing a Quadratic Function
A dog trainer is fencing in an enclosure, represented by the shaded
region in the diagram. The trainer will also have two square-chaped
storage units on either side of the enclosure to store equipment and
other materials. She can make the enclosure and storage units as
wide as she wants, but she can't exceed 100 feet in total length.
100 ft
Cet w represent the width, in feet, of one of the storage units. Write
a function Alwto represent the area as a function of width. Recall
that Area is width times Length.
On the next page see how the function for Area is written. Explain
how they got the two linear expressions:
