Answer to Question #179467 in Algebra for Paul Carpenter

Question

Reflect on the concept of function. What concepts (only the names) did you need to accommodate the concept of function in your mind? What is the simplest function you can imagine? In your day to day, is there any occurring fact that can be interpreted as a function? Is it possible to view a function? What strategy are you using to get the graph of a function?

Answer 1

A function is an expression, law, or rule that shows the relationship between two variables. The simplest function that one can imagine is y=x. One of the activities in our daily life that can be viewed as a function is the price and quality of goods and services. Functions cannot be seen but can be visualized by the use of graphs. The strategy used to plot a graph of a function is by creating a table by using the function to determine the values of the dependent variable using arbitrary points of the independent variables. If the function is linear a minimum of two points is required to represent the function graphically.
