- absolute-value inequality
- an equation that includes absolute value; it will have two solutions
- conjunction
- a type of compound inequality involving AND, and has an intersection
- line of reflection
- a horizontal line across the y-intercept of the parent-function
- parent function
- the most basic absolute value function: y = /x/
- absolute value
- the distance of a number from zero
- reflection
- the mirror image of the parent-function graph across the line of reflection
- disjunction
- a type of compound inequality involving OR, and has a union
- transformations
- the change of the function rule for the parent function
- union
- the total of the solution regions of the separate parts of the inequality (its when the two lines go opposite ways, not touching each other)
- absolute value function
- a function written in the form y = /x/, and the graph is always in the shape of a v
- inequality
- a statement that two expressions are not equal
- intersection
- an overlap of the solution regions for the separate parts of the inequality
- compound inequality
- the combination of two inequalities in one statement
- translation
- the shift of the parent-function graph horizontally or vertically
