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
