Introduction To Function Pdf Function Mathematics Equations Find the domain and range of a function. determine whether a relation is a function. use the vertical line test to determine whether a graph is the graph of a function. express functions using proper functional notation. This document provides an introduction to functions and function notation for a grade 11 mathematics unit. it defines what a function is, how functions can be represented using different notations like f (x), and how functions relate inputs to outputs.
Function Pdf Function Mathematics Equations Key point a function is a rule that maps a number to another unique number. the input to the function is called the independent variable, and is also called the argument of the function. the output of the function is called the dependent variable. Before we begin, we need to review the concept of what a function is and look at the rules that a function must follow. we also need to investigate the different ways that we can represent a function. = f (x) will be a function. for that reason, we thin of f as being the function. so we can think of a function as a machine that has an input of a real number and a single output as the real umber value of the function. the domain of a function is the set of possible input values (usually an interval), and the range of a function. Objectives graph ordered pairs in the coordinate plane. graph functions from ordered pairs. vocabulary coordinate plane axes origin x axis.

One easy way to determine if an equation in two variable is a function is to utilize the vertical line test. it is used on the graphs of equations in two variables to prove or disprove that they are functions. Here are a few examples of functions. we will look at them in more detail during the lecture. very important are polynomials, trigonometric functions, the exponential and logarithmic function. you won't nd the h exponential in any textbook. we will have a bit of fun with them later. In the beginning such language may seem awkward. we will now introduce the idea of domain and range. domain is the set of real numbers that can be put into given function, and range is the set of real numbers that can possibly come out of the function. Objectives: distinguish between independent and dependent variables. define and identify relations and functions. find the domain and range. identify functions defined by graphs and equations.
