Algebra 2 Chapter 8 Flashcards

Combined Variation

• Describes scenarios where one variable changes directly in relation to two or more other variables.

Complex Fraction

• Defined as a rational expression that includes a fraction within its numerator and/or denominator.

Constant of Variation

• Represented as K, it indicates the rate at which one quantity varies in relation to another.

Direct Variation

• A mathematical relationship where an increase in one variable leads to an increase in another, represented by the equation Y = kX.

Horizontal Asymptote

• A line that may be intersected by a graph, which approaches the line on the left and right sides but does not necessarily stay close.

Hyperbola

• Defined by the equation f(x) = 1/x, serving as the reciprocal function in algebra.

Inverse Variation

• Illustrates a relationship where one variable increases while the other decreases, maintaining a constant product, expressed by the equation y = k/x.

Joint Variation

• A form of variation where a variable changes directly in proportion to the product of two or more other variables.

Oblique Asymptote

• Also known as a slant asymptote, it represents an asymptote that is neither horizontal nor vertical.

Point of Discontinuity

• Identified as a specific point where a function lacks continuity.

Rational Equation

• An equation featuring one or more rational expressions, often complex in nature.

Rational Expression

• Defined as the quotient of two polynomials, forming a fundamental aspect of rational functions.

Rational Function

• A function characterized by being the ratio of two polynomial expressions.

Rational Inequality

• A type of inequality that consists of one or more rational expressions, often requiring specific solutions.

Reciprocal Function

• The parent function of inverse variation equations, forming the basis for understanding this type of relationship.

Vertical Asymptote

• A line that a graph cannot cross, with the graph approaching the line without intersecting it.

Weighted Average

• The mean of a group of numbers, where some numbers are given more significance compared to others, affecting the overall average calculation.
