Chapter 2- Graphs, Equations & Inequalities

Opposites

Two numbers on a number line that are equal distance from 0 but in different directions

equivalent compound inequality

a compound inequality that is equivalent

Absolute Value

a numbers distance away from 0 on a number line

Conjunction

a<x>b where a and b are real numbers, the part of the solution that satisfies both inequalities

compound inequality

an inequality that is formed by the union, "or", or the intersection "and", of two simple inqualities

solve an inequalities

function notation, f(x)=ax+b

Solve of a Compound Inequality

written in the form a<x>b, surrounding x with both inequalities on either side

Linear Absolute Value inequality

linear absolute value equation with inequalities

First Differences

the difference between the first two successive points/ unit rate of change

Intersection Point

the solution that satisfies both functions at the same time

Solution

the value that makes the sentence true

Linear Absolute value equation

two equations written can be represented by a linear absolute value equation l w-145.045 l = 3.295

Disjunction

x>a or x>b where a and b are real numbers, is the part or parts of the solution that satisfy either inequality
