37 terms

coordinate plane

A coordinate system formed by the intersection of a horizontal number line, called the x-axis, and a vertical number line, called the y-axis.

ordered pair

A pair of numbers, (x, y), that indicate the position of a point on a Cartesian plane.

term

a number, a variable, or the product of a number and a variable

variable

A letter or symbol used to represent a number.

sum

a quantity obtained by addition

difference

the number that remains after subtraction

quotient

the number obtained by division

product

a quantity obtained by multiplication

coefficient

number in front of a variable

constant

a quantity that does not vary

domain

the set of values of the independent variable for which a function is defined

range

The y-coordinates of the set of points on a graph. Also, the y-coordinates of a given set of ordered pairs. The range is the output in a function or a relation.

combine like terms

add or subtract the coefficients of the variables

algebraic expression

A mathematical phrase involving at least one variable and sometimes numbers and operation symbols.

integer

The set of whole numbers and their opposites

function

an input-output relationship that has exactly one output for each input

operation

calculation by mathematical methods

expression

a group of symbols that make a mathematical statement

exponent

indicates the number of times a quantity is multiplied by itself

square number

the product of a number and itself

slope

the steepness of a line on a graph, equal to its vertical change divided by its horizontal change

y-intercept

where the line crosses the y axis

monomial

an expression with only one term

polynomial

a mathematical expression that is the sum of a number of terms

linear equation

a polynomial equation of the first degree

Intercept

the point at which a line intersects a coordinate axis

Intersecting lines

Lines that cross

Minimum

the smallest possible quantity

Maximum

the largest possible quantity

Constant Difference

the difference that is always the same from one term to the next number

Negative Exponent

an exponent less than zero which causes the base and its exponent to move positions in a fraction

Slope

the steepness of a line on a graph, equal to its vertical change divided by its horizontal change

Quadratic Function

a function that can be written in the form f(x)=ax^2+bx+c, where a, b & c are real numbers and a is not equal to zero

Exponential Function

a function in which an independent variable appears as an exponent

Square Root Function

A function that contains a square root of a variable.

Cubic Functions

Third degree polynomial functions.

Axis of Symmetry

a line that divides a figure into 2 congruent parts
