Algebra 2 Graphing Flashcards

Graphing Concepts in Algebra 2

• The origin of a coordinate plane is the point located at (0,0).
• The x-axis represents the horizontal line in a Cartesian coordinate system.
• Domain refers to the complete set of all possible first coordinates in a relation or function.
• The Vertical Line Test is a method to determine if a graph represents a function; if any vertical line intersects the graph more than once, it is not a function.
• The abscissa, also known as the x-coordinate, is the first number in an ordered pair.
• The quadrants of the coordinate plane are divided into four sections, labeled by Roman numerals I through IV, counterclockwise.
• Range is the set of all possible second coordinates in a function or relation.
• Example of function notation: f(x) = 2x - 3, which allows for easy evaluation like finding f(4).
• Ordered pairs consist of two values and are used to accurately plot points on the coordinate plane.
• René Descartes was a mathematician known for developing the principles of coordinate geometry, which laid the groundwork for modern graphing techniques.
• Mapping is a visual representation that uses ovals and arrows to illustrate the relationship between sets of ordered pairs.
• A relation is any collection of ordered pairs, without the restriction of the unique second coordinate.
• A function is a specific type of relation in which every first coordinate corresponds to a unique second coordinate.
• The numbering of quadrants is done in a counterclockwise direction, starting from the upper-right quadrant, labeled with Roman numerals.
• A continuous function is one that can be represented by a smooth, unbroken curve on a graph.
• The Cartesian coordinate plane is named after French mathematician René Descartes, known for his contributions to algebra and geometry.
• Dots are the graphical representations used for discrete functions, which consist of distinct and separate points.
