turning points

Front

Point at which a graph turns

Back

dependent variable

Front

The other variable in a function, usually y, whose values depend on x

Back

translation

Front

A figure is slid from one location to another on the coordinate plane without changing its size, shape, or orientation

Back

vertical line test

Front

If no vertical line intersects a graph in more than one point, then the graph represents a function

Back

one-to one function

Front

A function where each element of the range is paired with exactly one element of the domain

Back

quadratic function

Front

a function described by the equation f(x)=ax2+bx+c, where a does not equal 0

Back

line symmetry

Front

Figures that match exactly when folded in half

Back

linear equation

Front

An equation that has no operations other than addition, subtraction, and multiplication of a variable by a constant

Back

onto function

Front

Each element of the range corresponds to an element of the domain

Back

x-intercept

Front

the x-coordinate of a point where a graph crosses the x-axis

Back

y-intercept

Front

the y-coordinate of a point where a graph crosses the y-axis

Back

zero of a function

Front

the x-intercept of the graph of a function

Back

relative minimum

Front

A point on the graph of a function where no other nearby points have a lesser y-coordinate

Back

greatest integer function

Front

A step function, written as f(x)=[[x]], where f(x) is the greatest integer less than or equal to x.

Back

linear function

Front

A function whose ordered pairs satisfy a linear equation

Back

domain

Front

The set of all x-coordinates of the ordered pairs of a relation

Back

relative maximum

Front

A point on the graph of a function where no other nearby points have a greater y-coordinate

Back

line of reflection

Front

The line over which a reflection flips a figure

Back

dilation

Front

A transformation in which a geometric figure is enlarged or reduced

Back

absolute value functiion

Front

A function written as f(x) = |x|

Back

reflection

Front

A transformation in which every point of a figure is mapped to a corresponding image across a line of symmetry

Back

point of symmetry

Front

The common point of reflection for all points of a figure

Back

parent graph

piecewise-linear function

Front

A function in which the equation for each interval is linear

Back

line of symmetry

Front

A line that divides a figure into two halves that are reflections of each other

Back

continuous relation

Front

A relation that can be graphed with a line or smooth curve.

Back

parent function

Front

The simplest, most general function in a family of functions.

Back

discrete relation

Front

A relation in which the domin is a set of individual points

Back

step function

Front

A function whose graph is a series of line segments

Back

point symmetry

Front

Two distinct points P and P' are symmetric with respect to point M if and only if M is the midpoint of PP'

Back

function notation

Front

An equation of y in terms of x can be rewritten so that y = f(x)

Back

piecewise-defined function

Front

A function that is written using two or more expressions

Back

end behavior

Front

The behavior of the graph as x approaches positive infinity or negative infinity

Back

independent variable

Front

In a function, the variable, usually x, whose values make up the domain
