Study Notes

Rational Numbers

Rational numbers can be expressed as integers or fractions and have terminating decimals. Example: 6.2.

Continuous Graphs

Continuous graphs permit x-values to be any point within a given interval, including fractions and decimals. Example: For x = 1.2, y = 3 corresponds to point (1.2, 3).

Maximum Turning Point

A maximum turning point signifies a relative maximum in a polynomial graph where the output begins to decrease.

Absolute Value

Represents the distance of a number from zero on the number line.

Discrete Graphs

Discrete graphs include x-values as specific points, commonly integers. Example: For x = 1, y = 3 corresponds to point (1, 3).

Sum

The sum refers to the result of adding numbers together. Example: 2 + 2 = 4.

Monomial

A monomial consists of a single term. Examples include 12, 12xy, or x.

Function

Functions are relations where each input corresponds to one unique output. Verified through the vertical line test. Example: x = 3 corresponds to y = 2.

Causation

Causation indicates the influence one variable has over another, shown as the relationship between input (x) and output (y).

Bivariate Data

Bivariate data involves two variables where each value of one variable pairs with a corresponding value of another.

Conjugate Pair

A conjugate pair consists of two binomials differing only in their signs. Example: (2x + 4)(2x - 4).

Quartiles

Quartiles divide a dataset into four equal parts, with medians separating upper and lower quartiles.

Zero Property Factor

This property states that if the product of two numbers equals zero, at least one of the factors must be zero. Utilized in factoring.

Irrational Numbers

Irrational numbers cannot be expressed as simple fractions, often represented by non-terminating decimals. Example: π.

Linear Functions

Linear functions produce straight-line graphs and include variables raised only to the power of 1. Examples: y = x, y = mx + b.

Minimum Turning Point

A minimum turning point signifies a relative minimum value in a polynomial function, where the output begins to increase.

Substitution Method

A technique for solving linear systems, involving solving for one variable and substituting that value into another equation. Example: Solve 3x + y = 10 and 2x + 2y = 8.

Constraints

Constraints denote limitations on variables, often expressed through inequalities representing greater or lesser values.

Turning Points

Turning points in polynomial functions indicate where the graph changes direction, such as starting to increase or decrease.

Interval Notation

Interval notation indicates a range of numbers defined by two endpoints, illustrating the x-values fulfilling an inequality.

Linear Regression

Linear regression models the relationship between a dependent variable and one or more independent variables through a line of best fit.

Multiplicative Property of Equality

This property signifies that both sides of an equation remain equal when both are multiplied by the same non-zero quantity. Example: If x = 4, then 2x = 8.

Symmetry

Symmetry is observed when parts of a figure or graph are identical after transformation (flip, slide, turn), resembling mirror images.

Recursive Definition

A recursive definition is a formula linking sequential terms, where a current term depends on the previous term’s value.

Rate of Growth

The rate of growth indicates how much a function increases over time, typically visible through the slope of a line.

Elimination Method

The elimination method is a strategy for solving linear systems where one variable is canceled out when equations are added.
