A public adjuster is a self-employed claims adjuster who determines how much insurance companies should pay for losses incurred by policy holders. Public adjusters are usually hired by claimants who don't want to use an adjuster associated with their insurance company. In such cases, it's your job to make sure that your clients get as much money as possible from their claims.
Parabolas that open up or open down have what is referred to as minimum and maximum value. The maximum value of a parabola is the y-coordinate of the vertex of a parabola that opens down. The minimum value of a parabola is the y-coordinate of the vertex of a parabola that opens up. We can identify the minimum or maximum value of a parabola by identifying the y-coordinate of the vertex. Take a look at this graph. The vertex is located at the point (2.5, -.5), and the parabola opens up. That means that the parabola has a minimum value, which is y = 2.5.
In other words, line l1 from the directrix to the parabola is the same length as l1 from the parabola back to the focus. The same goes for all of the other distance from a point on the parabola to the focus and directrix. You probably know that the smaller |a| in the standard form equation of a parabola, the wider the parabola. In other words y = .1xÂ² is a wider parabola than y = .2xÂ² and y = -.1xÂ² is a wider parabola than y = .-2xÂ² . You can understand this 'widening' effect in terms of the focus and directrix. As the distance between the focus and directrix increases, |a| decreases which means the parabola widens.
