linear equations and inequalities

Functions and Linear Equations and Inequalities
Today let me help you on linear equations and inequalities. A mathematical function is an equation which assigns a single answer to each possible question. A variable denotes as an unknown value in the functions and equation.

Example for functions:
The set of all element in functions and ordered pairs is known as domain; the set of all second elements are called range.This could also help us on how to make a circle graph

Example:
Functions f(x) = {(1 , 2), (3 , 4), (5 , 6), (7 , 8)}
Here Domain = { 1, 3, 5, 7 } and
Range = { 2, 4, 6, 8 }
