Back

Range

Front

The possible values for the output of a relation (the y values)

Back

Domain

Front

The possible values for the input of a relation (the x values)

Back

Function

Front

A relation that assigns exactly one value in the range to each value of the domain

Back

Parabola

Front

The graph of a quadratic function

Back

System of Equations

Front

Two or more equations using the same variables

Back

Reciprocal

Front

The multiplicative inverse of a number (fraction turned upside down)

Back

Point Slope Form

Front

Back

Undefined Slope

Front

The graph of a vertical line

Back

Coefficient

Front

The number before the variable

Front

All non zero numbers raised to the zero power equal 1

Back

Quadratic Formula

Front

Back

Shading 1/2 Planes When Graphing Inequalities

Front

Use the test point (0,0), if (0,0) is a solution, shade the area on that side of the boundary. If (0,0) is not a solution, shade the area on the other side of the boundary.

Back

Literal Equation

Front

An equation involving two or more variables

Back

Completing the Square

Front

A method used to solve Quadratic equations, best to use when a=1 but the problem can not be factored.

Back

Diamond Method Factoring

Front

Place the constant in the top section, the coefficient of x2 in the bottom section. Find two numbers whose product is the the top number and whose sum is the bottom number.

Back

FOIL

Front

First, Outside, Inside, Last (used to multiply two binomials)

Back

Multiply and Divide Exponents with the Same Base

Front

To multiply powers with the same base, add the exponents. To divide powers with the same base, subtract the exponents.

Back

Slide / Divide /Bottoms Up

Front

A method used to solve Quadratic equations with a > 1. SLIDE: multiply the leading coefficient by the constant. DIVIDE: divide the constants of the factors by the original leading coefficient. BOTTOMS UP: move the denominator of simplified fractions to the front of the x in the binomial.

Back

Golden Rule of Inequalities

Front

Whenever you multiply or divide by a negative number, flip the direction of the inequality symbol

Back

Rate of Change

Front

The relationship between two quantities that are changing (Slope)

Back

Front

Back

Vertical Line Test

Front

Used to determine if a relation is a function or not

Back

Slopes of Perpendicular Lines

Front

Perpendicular lines have slopes whose product is -1 (their slopes are opposite reciprocals)

Back

Front

Back

Explicit Formula of a Geometric Sequence

Front

Back

Front

Back

Slopes of Parallel Lines

Front
