DESCRIBING GRAPHS AND CHARTS The function of a line graph is to describe a TREND pictorially. You therefore should try and describe the trend in it. If there are many lines in the graph(s)‚ then just generally describe the trend. If there is only one or two‚ then use more detail. So‚ describe the movement of the line(s) of the graph giving numerical detail at the important points of the line. To describe the movement‚ there is some language which will always be useful. Below is a list of language

Homework #1 (each 4 points) 1. At his death in 1790‚ Benjamin Franklin left 1‚000 pounds each to the cities of Boston and Philadelphia on the condition that they would not touch the money for 100 years. Boston’s bequest‚ which was equivalent to about $4‚600‚ had ballooned to $332‚000 by 1890. a. Determine the equivalent annual rate of return between 1790 and 1890. b. If the city of Boston had left this bequest in a fund earning 5% per year between 1890 and 1990‚ what would have been the value of

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

Graphs‚ Groups and Surfaces 1 Introduction In this paper‚ we will discuss the interactions among graphs‚ groups and surfaces. For any given graph‚ we know that there is an automorphism group associated with it. On the other hand‚ for any group‚ we could associate with it a graph representation‚ namely a Cayley graph of presentations of the group. We will first describe such a correspondence. Also‚ a graph is always embeddable in some surface. So we will then focus on properties of graphs

ABC System in Super Bakery Inc. (Introduction) – What strategies did the management of Super Bakery‚ Inc. use? Installation of the Activity-Based Costing System Super Bakery was formed in the 1980’s during a time when the barrier to entry into the baked goods industry was limited. They started the company using the industry’s standards and following them very strictly. The first four years of Super Bakery were not profitable and management knew they had to make changes so the company could

------------------------------------------------- ------------------------------------------------- Speed Speed is defined as a measure of the distance an object travels in a given length of time. The average speed of an object can be determined from the equation below: Thus‚ if a car travels 100 meters in 5 seconds its average speed can be calculated as; Average speed = 100/5 = 20 meters per second Average speed is used to give the speed of an object over a given interval of time‚ if

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
