Write a function rule from the table below

Introduction Quite often I see a question in a newsgroup or forum along the lines of: What is this thing called 'OOP'? What is so special about it? Why should I use it?

How do I use it? The person asking this type of question usually has experience of non-OO programming and wants to know the benefits of making the switch.

Unfortunately most of the replies I have seen have been long on words but short on substance, full of airy-fairy, wishy-washy, meaningless phrases which are absolutely no use at all to man or beast. According to some OO 'purists' I am not qualified at all as I was not taught to do things 'their' way and I refuse to follow 'their' methods.

My response to that accusation is that there is no such thing as 'only one true way' with OOP just as there is no such thing as 'only one true way' with religion. People tell me that my methods are wrong, but they are making a classic mistake. My methods cannot be wrong for the simple reason that they workand anybody with more than two brain cells to rub together will tell you that something that works cannot be wrong just as something that does not work cannot be right.

My methods are not wrongthey are simply differentand sometimes it is a willingness to adopt a different approach that separates the code monkeys from the engineers.

One reason why some people give totally useless answers is that it was what they were taught, and they do not have the intelligence to look beyond what they were taught. Another reason is that some of the explanations about OO are rather vague and can be interpreted in several ways, and if something is open to interpretation it is also open to a great deal of mis -interpretation.

Even some of the basic terminology can mean different things to different people, as explained in Abstraction, Encapsulation, and Information Hiding. If these people cannot agree on the basic concepts of OOP, then how can they possibly agree on how those concepts may be implemented.

In compiling the following list I picked out those descriptions which are not actually unique to OOP as those features which already exist in non-OO languages cannot be used to differentiate between the two.

OOP is about modeling the 'real world' OOP is a programming paradigm that uses abstraction to create models based on the real world.

It provides for better modeling of the real world by providing a much needed improvement in domain analysis and then integration with system design. OOP is no better at modeling the real world than any other method.

Every computer program which seeks to replace a manual process is based on a conceptual software model of that process, and if the model is wrong then the software will also be wrong.

The conceptual model is created as an analyst's view of the real world, and the computer software is based solely on this conceptual model. OOP does not provide the ability to model objects which could not be modelled in previous paradigms, it simply provides the ability to produce different types of models where both the data and the operations which act upon that data can be defined encapsulated in the same unit class.

OOP does not guarantee that the model will be better, just that the implementation of that model will be different. You should also consider the fact that it would be totally impractical to model the whole of the real world as it is simply too vast and too complicated.

It is only ever necessary to model those parts which are actually relevant to your current application, and it is the exercise of deciding what is and is not relevant which decides if your abstraction is correct.

Bear in mind that unless you are developing software which directly manipulates a real-world object, such as process control, robotics, avionics or missile guidance systems, then some of the properties and methods which apply to that real-world object may be completely irrelevant in your software representation.

If, for example, you are developing an enterprise application such as Sales Order Processing which deals with entities such as Products, Customers and Orders, you are only manipulating the information about those entities and not the actual entities themselves.

In pre-computer days this information was held on paper documents, but nowadays it is held in a database in the form of tables, columns and relationships.

An object in the real world may have many properties and methods, but in the software representation it may only need a small subset.

For example, an organisation may sell many different products with each having different properties, but all that the software may require to maintain is an identity, a description and a price.

A real person may have operations such as stand, sit, walk, and run, but these operations would never be needed in an enterprise application.

Regardless of the operations that can be performed on a real-world object, with a database table the only operations that can be performed are Create, Read, Update and Delete CRUD. Following the process called data normalisation the information for an entity may need to be split across several tables, each with its own columns, constraints and relationships.

Each object in the database is a separate table, so I see no reason why I should not have a separate class in my software to deal with each object in my database.May 17,  · 1. Explain how to write a function rule from the table below.

Then write a function. x| 2, 4, 6 y| 1, 0, -1 2. Write a quadratic rule for the data in the leslutinsduphoenix.com: Open. Rounding a numerical value means replacing it by another value that is approximately equal but has a shorter, simpler, or more explicit representation; for example, replacing $ with $, or the fraction / with 1/3, or the expression √ 2 with Rounding is often done to obtain a value that is easier to report and communicate than the original.

Explain how to write a function rule from the table below. Then write a function rule. X: 2 | 4| 6 | And: 1 | 0 | -1 | My Answer: y = -1/2 x But, -1/2 (2) = -1, and y(2) = 1, so we need to add 2 at the start. Each function is a rule, so each function table has a rule that describes the relationship between the inputs and the outputs.

Sometimes a rule is best described in words, and other times, it is. SAP NetWeaver AS ABAP Release , ©Copyright SAP AG. All rights reserved.
