    Study Notes

    Algebra Concepts

    • Arithmetic Sequence Formula: an = a1 + (n-1)d, used to find the nth term in an arithmetic sequence.
    • Geometric Sequence Formula: an = a1(r)^(n-1), used for determining terms in a geometric sequence.
    • Exponential Function: Represented as y = 3^x, a function where the variable is an exponent.
    • Quadratic Function: Expressed as y = x^2, a polynomial function of degree 2, forming a parabola.
    • Linear Function: Defined by y = mx + b, where m is the slope and b the y-intercept.

    Key Mathematical Terms

    • Prime: A whole number greater than 1 that has no positive divisors other than 1 and itself.
    • Perfect Square: A number that can be expressed as the square of an integer.
    • Inequalities Symbols: "<" indicates "less than" with a dashed line and shading downward; ">" indicates "greater than" with a dashed line and shading upward.
    • Sum, Product, Difference, Quotient: Terms describing the results of addition, multiplication, subtraction, and division, respectively.

    Statistics and Properties

    • Mean: The average of a set of numbers.
    • Mode: The number that occurs most frequently in a data set.
    • Median: The middle value in a set of numbers.
    • Quadrant: One of four sections in the coordinate plane, defined by the x and y axes.

    Algebraic Properties

    • Commutative Property: a + b = b + a, demonstrating that addition is independent of order.
    • Associative Property: (a + b) + c = a + (b + c), showing grouping does not affect the result in addition.
    • Distributive Property: a(b + c) = ab + ac, illustrating how multiplication distributes over addition.
    • Property of Equality: A principle stating that actions performed on one side of an equation must be performed on the other side.

    Functions and Equations

    • Lead Coefficient: The coefficient in front of the variable with the highest exponent in a polynomial.
    • System of Equations: A set of two or more equations with the same variables.
    • Derivative Concepts: In the context of y = ax + b, "a" signifies the slope while "b" signifies the y-intercept.
    • Function Identification: The Vertical Line Test is used to determine if a graph represents a function.

    Calculator Functions

    • STAT Key: Utilized to compute mean and median values.
    • Creating Tables: The keys STAT and EDIT enable the user to generate data tables.
    • Fraction Box Creation: Keys ALPHA and Y= facilitate the creation of fraction boxes in calculations.

    Expressions and Evaluations

    • Quadratic Expansions: Examples provided include:
      • (x + 2)(x + 7) = x^2 + 9x + 14
      • (x - 6)(x - 6) = x^2 - 12x + 36
    • Function Evaluations: Examples of evaluating functions at given points:
      • f(x) = 3x + 2; find f(4) = 14
      • g(x) = x - 7; find g(0) = -7

    Graphs and Functions

    • Ordered Pairs: Understanding conditions under which a set of points constitutes a function and identifying pairs that disrupt this criterion, like (2, 6) when (2, 3), (3, 4), and (4, 5) exist.
