Study Notes

Flashcards Overview

  • Collection of definitions and functions related to algebraic concepts.

Function Identifications

  • Card 10: Represents a relation that is not a function.
  • Card 11: Again identifies a relation that is not a function.
  • Card 12: Defines a relation as a function, implying each input corresponds to exactly one output.

Linear Equations

  • Card 14: Linear function represented as y = 4x + 3.
  • Card 15: Linear function represented as y = 2x - 3.
  • Card 16: Linear function represented as y = -1/2 x + 7.

Polynomial Expressions

  • Card 17: Polynomial function expressed as x² + x - 11.
  • Card 18: Polynomial function expressed as x³ + x² - 9x - 9.
  • Card 19: Polynomial function expressed as x² + 12x + 29.
  • Card 20: Polynomial function expressed as x² + 2x - 1.

Value Ranges and Intervals

  • Card 21: Represents the interval (-∞, ∞), indicating all real numbers.
  • Card 22: Denotes another interval (-∞, ∞), showing complete range.
  • Card 23: Closed interval (-2, ∞), starting from -2 to positive infinity.
  • Card 24: Represents the closed interval [6, 6], containing a single point.
  • Card 25: Interval [1, ∞), starting from 1 to infinity.
  • Card 26: Open interval (2, ∞), starting just above 2 to infinity.

Constant Functions

  • Card 27: Defines a constant function represented by the line y = 7.
  • Card 28: Another constant function described by the line y = 10.

Vertex and Reflection Points

  • Card 29: Describes a vertex of a parabola located at (-2, -3), with respective mirror points at (-3, -2) and (-4, 1).
