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.
