    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).
