Many factors determine the design of a business district. Some of these factors deal with function and form. If a building’s purpose is for the sale of warehouse items, the building must be designed with enough room for large amounts of merchandise and customers. In the case of a warehouse supercentre, the space requirement is far greater than that of a specialty-item store, for example.

 

Other factors that influence the design of a new development include

  • cost
  • potential returns on investment
  • maintenance and upkeep

These factors are addressed in a feasibility study at the onset of the project, before any construction begins. This allows investors and other stakeholders to see the big picture before committing to the project.

 

In Module 3 you studied the properties of quadratic functions and their graphs. The graph of a parabola, like a big picture, can tell you much about the quadratic function the graph represents. The graph of a parabola can also help you solve a quadratic equation.
