Every parabola has an axis of symmetry which is the line that runs down its 'center'. This line divides the graph into two perfect halves. Explore how the graph and equation relate to the axis of symmetry, by using our interactive program below.
All deliveries to a Business Address will continue to require a signature upon delivery. However, deliveries to Residential Addresses do not require a signature regardless of the type of delivery (Ground or Express). The FedEx driver has discretion over whether or not to leave the package at the front door.
If a qualified person is not available to sign for the first delivery attempt, the USPS carrier leaves a Delivery Attempt Notice (PS Form 3849) which notifies the addressee that an article requiring a signature is being held for them at the Post Office and will be available for pick-up the following business day.
