Creating an Input/Output Table of Values
Introduction to Functions
range |
the set of output values corresponding to the domain values |
dependent variable |
the variable in a function that represents the output values; the second coordinate in the ordered pairs |
function |
a relation in which each element of the domain is mapped to (paired with) exactly one element of the range |
domain |
the set of input values for which the function is defined |
relation |
a set of ordered pairs |
independent variable |
the variable in a function that represents the input values; the first coordinate in the ordered pairs |
Continuous vs. Discrete Graphs
Writing and Graphing Equations in Two Variables
assume |
to accept as true without proof |
viable |
capable of working successfully; practical, realistic, usable, possible |
continuous graph |
a graph in the coordinate plane made up of connected ines or curves with no breaks |
coordinate plane |
a graph that has a finite number of data points |
ordered pair |
the pair of numbers, given in a specific order used to locate a point a coordinate plane |

Creating an Input/Output Table of Values
Domain is x-axis, while Range is y-xis
Is it a function? Do the vertical line test
Definitions
discrete graph |
a graph that has a finite or limited number of data points |
function notation |
a notation that traditionally replaces the dependent variable in a function with đť‘“đť‘“(đť‘Ąđť‘Ą), where đť‘“đť‘“represents the valueof the dependent variable at a given independent value, đť‘Ąđť‘Ą |
continuous graph |
a graph in the coordinate plane made up of connected lines or curves with no breaks |
