What is the Domain?
{-3, -1, 1, 3, 5, 7, 9}
{-3, -2, -1, 0, 1, 2, 3}
{3, 2, 1, 0, -1, -3}
{2, 1, 0, -2, -3}
For the function (0,1), (1,-3), (2,-4), & (-4,1), which choice gives the correct domain & range?
Remember:
Domain is x and Range is y
D: {0, 1, 2, -4}
R: {1, -3, -4, 1}
D: {-4, 0, 1, 2}
R: {-4, -3, 1}
D: {0, 1, 2, 3, 4}
R: {1, -3, -4}
D: {-4, -3, 1}
R: {-4, 0, 1, 2}
What is the range of the following graph?
R: {-5, -1, 0 , 1, 5}
R: {-4, -2, 0, 3, 6}
R: {-4, 1, 6, 5, 0}
R: {6, 0}
What is the Range?
{-3, -1, 1, 3, 5, 7, 9}
{-3, -2, -1, 0, 1, 2, 3}
{9,7, 5,3,1, -3}
{-3, 1, 0, 3, 5}
Is this mapping a function and how can you tell?
Yes its a function cause all the numbers have lines
No it's not a function because there a 5 in both ovals
No it's not a function because the x value 5 has 2 outputs.
No it's not a function because the y value 5 has 2 inputs.
Is this table a function and how can you tell?
Yes its a function because there are not variables for missing numbers
No it's not a function because the y value 4 repeated
No it isn't a function because the x value 2 is repeated
No it's not a function because the x value 5 has 2 outputs.
Which is the INDEPENDENT value? (Hint: DIXI ROYD)
Domain
Range
Which is the DEPENDENT value? (Hint: DIXI ROYD)
Domain
Range
What does "DIXI" stand for?
Domain, input, X-values, IR
Dependent, Input, X-values, Independent
Domain, input, x-values, indigo
Domain, Input, X-values, Independent
What does "ROYD" stand for?
Range, Output, Y-values, Dependent
Range, OR, Y-values, Dependent
Range, Output, Y-values, Domain
Real, Output, Y-values, Dependent
Is this a function and why?
Function, passes the vertical line test
Not a Function, fails the vertical line test
Not a Function, passes the vertical line test
Function, fails the vertical line test
What is the definition of function?
Has inputs and outputs
Every input has only ONE output
Input have different outputs every time
x-values and y-values
The vertical line test passes when the vertical line crosses the graph how many times:
one time
two times
three times
not at all
For the function (0,3), (5,-3), (2,-8), & (-7,1), which choice gives the correct domain & range?

D: {-7, 0, 5, 2}
R: {-8, -3, 1}
D: {-7, 0, 2, 5}
R: {-8, -3, 1, 3}
D: {-7, 3, 5}
R: {-8, 0, 1, 3}
