1.2 Basics of Functions and Their Graphs Introduction to Relations Domain and Range of a Relation Any set of ordered pairs (x‚y) is called a relation in x and y. Furthermore‚ The set of first components in the ordered pairs is called the domain of the relation. The set of second components in the ordered pairs is called the range of the relation. Definition of Function and Vertical Line Test Definition of a Function Given a relation in x and y‚ we say “y is a function of x” if for every

INTRODUCTION Gozinto Chart named after an Italian mathematician Professor Zepartzat Gozinto is from the word ‘goes into’ is used to provide overall microview of how materials and subassemblies are united to form finished products. It is often called Assembly chart (Shim and Siegel‚ 1999) In other words‚ it is a pictorial representation of a product that shows how the elements required to build a product fit together. Gozinto Chart is a schematic model that defines how parts go together‚ the order

Introduction in Graph Theory (BASIC CONCEPTS) BASIC CONCEPTS We used decision trees in Unit DT and used them to study decision making. However‚ we did not look at their structure as trees. In fact‚ we didn’t even define a tree precisely. What is a tree? It is a particular type of graph‚ which brings us to the subject of this unit. What is a Graph? There are various types of graphs‚ each with its own definition. Unfortunately‚ some people apply the term “graph” rather loosely‚ so

Pie Charts An important part of decision making is having a clear understanding of the information used to base decisions from. Charts can be valuable when a need to represent numerical data would benefit communicating information visually. Some of the most important aspects of a good chart are to select the right type of chart (or graph) that can best characterize the data‚ also‚ to keep the design simple in order for an audience to easily understand the information. One of the most popular types

The Qualitative Paradigm The design of a research study begins with the selection of a topic and a paradigm. A paradigm is essentially a worldview‚ a whole framework of beliefs‚ values and methods within which research takes place. It is this world view within which researchers work. According to Cresswell (1994) "A qualitative study is defined as an inquiry process of understanding a social or human problem‚ based on building a complex‚ holistic picture‚ formed with words‚ reporting detailed

Qualitative Methods And analysis * . Quantitative research is used widely in social sciences such as sociology‚ anthropology‚ and political science. Research in mathematical sciences such as physics is also ’quantitative’ by definition‚ though this use of the term differs in context. In the social sciences‚ the term relates to empirical methods‚ originating in both philosophical positivism and the history of statistics‚ which contrast qualitative research methods. Qualitative

Data Analysis: Graph 1 indicates the relationship between the dependent and the independent variable to be; as the concentration of sodium bicarbonate in the solution submerging the leaf discs is increased‚ the average rate of photosynthesis of the leaf discs increased in a linear trend. As it is the sodium bicarbonate which decomposes into carbon dioxide necessary for photosynthesis‚ it is reasonable to consider from Graph 1 that as carbon dioxide concentration of the solution increases‚ the rate
