Set Notation

• Uses a verbal description or an inequality to describe the numbers.

• Uses square brackets to enclose the elements.

• Represents numbers using only integers.

• Utilizes parentheses for grouping elements.

Horizontal Stretch/Shrink

• Pulls away from or pushes a graph toward the y-axis

• Changes the height of the graph

• Increases the slope of the graph

• Flips the graph over the x-axis

Ratio
