the portion of the x-axis used

#<x<#

a list of x values

Range

 the portion of the y-axis used

# < y < #

a list of y values

dependent

cost= 7 h + .05 s

dependent is left hand variable

cost = dependent

independent

cost= 7 h + .05 s

independent variables are on right side

h  &  s are independent

solutions, zeros, roots

where a graph crosses the

x-axis

y=x^2+5x+6

solution

-3,-2

function

Where no x value is repeated

vertical line test---line only passes through graph

once

Horizontal

like the horizon

__________________________

same direction as x-axis

vertical

a line up and down

like the y-axis

Commutative Property

a + b + c = b + c + a

order changes

Associative Property

(A + B) + C = A + (B + C)

what's in parentheses changes

theoretical

probablility

 what is the probability

taken straight from the object(s)

before they are touched

experimental

probability

data has been recorded in

a table, graph or list

use the data to determine the probability

of the event that has already occurred

x-intercept

where the graph crosses

the x-axis

(x , 0 )

y-intercept

where the graph crosses

the y-axis

( y , 0 )
