Site Navigation Finding the Mean, Median, and Mode When you hear someone use the word "average" to describe a set of numbers, be careful. A more accurate phrase to use is measure of central tendency.
Functions This section looks at functions within the wider topic of Algebra. A function may be thought of as a rule which takes each member x of a set and assigns, or maps it to the same value y known at its image.
The same notion may also be used to show how a function affects particular values. The phrase "y is a function of x" means that the value of y depends upon the value of x, so: On a graph, a function is one to one if any horizontal line cuts the graph only once.
Composing Functions fg means carry out function g, then function f.
To find the inverse of a function, swap the x"s and y"s and make y the subject of the formula. This video explains more about the inverse of a function Graphs Functions can be graphed. A function is continuous if its graph has no breaks in it.
A function is periodic if its graph repeats itself at regular intervals, this interval being known as the period. A function is even if it is unchanged when x is replaced by -x.
The graph of such a function will be symmetrical in the y-axis. Even functions which are polynomials have even degrees e. A function is odd if the sign of the function is changed when x is replaced by -x. The graph of the function will have rotational symmetry about the origin e. The Modulus Function The modulus of a number is the magnitude of that number.
For example, the modulus of -1 -1 is 1. The modulus of x, xis x for values of x which are positive and -x for values of x which are negative.The textbook Elementary Mathematics for Teachers is designed to be used in conjunction with the Primary Mathematics (U.S.

Section Writing Expressions 11 In , the number of members from Florida in the House of. For polynomials with integer coefficients the question is roughly the same as "what are the practical applications of algebraic number theory".
The usual answers are coding theory and cryptography where factorization (and related operations such as testing whether a polynomial can be factorized) is part of the basic infrastructure from which.
