Study Notes

Linear Equations

  • A linear equation has terms that include constants or the product of a constant and a single variable.

Polynomials

  • A polynomial is composed of constants and variables, connected through addition and multiplication operations.

Radical Equations

  • A radical equation features at least one radical expression, which includes a square root or other roots.

Quadratic Inequalities

  • Quadratic inequalities take the form of ax² + bx + c, where the relation includes inequality symbols such as ≥ or ≤.

Relations

  • A relation consists of a set of ordered pairs, demonstrating the connection between two sets of values.

Closure Property

  • Closure refers to the guarantee that performing an operation on members of a set will always result in another member of the same set.

Domain

  • The domain identifies the set of first coordinates (x-values) from each ordered pair in a relation.

Functions

  • A function is a specific type of relation where each element of the domain corresponds to exactly one element in the range, ensuring no repeated x-values.
