Define
A relationship that pairs each output with a different input value
Function
Find the domain
{(4,6),(7,-3),(4,-5),(3,0),(7,6)}
{4,7,3}
Independant variable
Represents the x value-can not be changed-use for word problems
Continuous graph
A graph that has a connected line when graphing the data. Data can have any value.
Not a function
a relationship that does not pair each output with a different input value
Find range
{(4,6),(7,-3),(4,-5),(3,0),(7,6)}
{6,-3,-5,0}
dependant variable
change in values of y-depend on the values of x-used in word problems.
Mapping Diagram
A diagram showing how the input and output values of a function are paired.
The way a function is written also known as (fx)
Function Notation
Where is a vertical line test used? What do we use it for?
A vertical line test is used on graphs. It is another way to describe if a relation is a function.
Input
Values put on any function
relation
A relationship that can be represented by a set of ordered pairs. Written in {(),()}
Linear Function
A function whose graph is part of a linear line. Solutions fall on a linear line.
Identify the function rule
fx=2x+7
Function rule: 2x+7
output
values that are the result of any function
Solution
A value that makes an eqaution true
a function whose graph is not part of a straight line
Non- linear
Ordered pair
The solution of a two-variable equation
Function rule
An algebraic expression that describes the relationships between the inpus and outputs
