Study Notes

Algebraic Concepts Overview

Algebraic Base: Number or variable raised to a power.
Domain: Set of all possible x-values in a function or relation.
Range: Set of all possible y-values in a function.
Function: Relation where each x-value corresponds to only one y-value.
Quadratic Equation: Polynomial equation where the variable is squared (degree 2).

Inequalities and Properties

Compound Inequality: Two inequalities combined with AND or OR.
Linear Inequality: Inequalities that can be graphed as lines, which may be dashed (not including) or solid (including).
Inequality Rule: When multiplying or dividing by a negative number, the inequality symbol must be reversed.
Absolute Value: Represents the distance of a number from zero.

Sequences and Series

Arithmetic Sequence: A sequence of numbers with a constant difference between consecutive terms.
Geometric Sequence: A sequence where each term is found by multiplying the previous term by a constant factor (not mentioned but commonly associated).

Mathematical Operations

Evaluate: Find the value of an expression using the order of operations (PEMDAS).
Estimation: Use rounding for reasonable approximations to calculate values without exact figures.
Coefficient: The numerical factor multiplying a variable in an expression.

Graphical Interpretations

Line of Best Fit: A line that best represents the data in a scatterplot.
Y-intercept: The point where a graph crosses the y-axis (where x = 0).
Slope: Change in y over change in x, indicating the steepness of a line.
Point-Slope Form: y - y1 = m(x - x1), a formula for the equation of a line based on a point and slope.

Number Types

Natural Numbers: Positive integers starting from 1 (i.e., {1, 2, 3, ...}).
Whole Numbers: Non-negative integers including zero (i.e., {0, 1, 2, ...}).
Integers: Positive and negative whole numbers including zero ({..., -3, -2, -1, 0, 1, 2, 3, ...}).
Rational Numbers: Numbers expressible as a fraction, including integers and finite or repeating decimals.
Irrational Numbers: Numbers that cannot be expressed as fractions, like √2 and π.

Set Theory and Functions

Union of Sets: Combining elements from two sets, represented as A U B.
Complement of a Set A: Elements not in set A, denoted by ~A.
Subset: A set where all members are contained within another larger set.
Venn Diagram: A visual representation of the relationships among sets.

Additional Concepts

Distributive Property: a(b + c) = ab + ac, showing how to multiply a single term across a sum.
Associative Property: (A + B) + C = A + (B + C), indicating that addition can be grouped freely.
Commutative Property: A + B = B + A or AB = BA, showing the addition or multiplication order doesn't affect the outcome.
Transformation: Operations such as reflection, translation, and stretching applied to functions.
Rate of Change: The ratio comparing the change in one quantity to the change in another quantity.

By focusing on these concepts, students can enhance their understanding of Algebra 1 for the Florida EOC.
