Input      Output        Is this relation a function?

1            2                              

1            2

2            4

3            6

The Relation is not a function.

domain: 1,2 and 3

Range: 2,4 and 6

not a Function because, the domain is duplicate.

61

Input       Output    Is it a function?

-4              -1

-12            -3

12              3

4                1


Yes

61

Input    Output     Is the relation? if so, what the  

12           182      domain and range

-12     -182

-6       -64

6         64

yes, 

Domain: 12,-12,-6,6

range: 182, -182, -64 and 64

61

Determine the relation is a function.

(-1/2,2), (-1/2,4), (1/3,7), (1/3, 9)

its not a function

Domain: -1/2, 1/3

Range: 2,4,7,9

61

Input     output        is there many solutions? why?

1              -1

2              -5

3               -9

4              -13

5                 _

_                 -17

The blanks are 5 and -17

and there is only one solution, because aything else would make it many

62

input, x -1 0 1 1 2

output, y -2, -1, 0,1 2

Is the relation a function yes or no.

if so give me the domain and range

is Not a function

domain:-1 0 1 2 

range: -2 -1 0 1 2

62

input x :  0 1 2 3 4 

output y : 4 6 8 10 12

is the relation a function? if so give me the domain and range.

Yes it is a Function

Domain: 0 1 2 3 4 

input: 4 6 8 10 12 

62

Input: 2 4 6 8 10

output: 2 2 3 3 4

Is the relation a function? if so give me the domain nd range

Yes it is.

Domain: 2 4 6 8 10

Input: 2 3 4

62

determine if the relation is a function(graph)

(3,4), (1,2), (-1,2), (-1, 0), (-3, -2) List domain and range

It is Not a function

Domain: -3 -1 1 -3

Range: -2 0 2 4 

62

Determine whether the graph is a function

(3,2), (0 ,-1) (3,-2), 

It is Not a function

Domain: -1<x and x<-3

Range: -2 < y and y < 2

63

use the graph to write a linear equation that relates to x and y.

(4,3), (2,0), (0,-3), (-2,6)


3-0= 3

4-2 =2      Linear function is y= 3/2 x -3

because the line crosses the y-axis (0,-3) the y intercept is -3

63

x: 2 4 6 8

y: -8 -4 4 8

Is the table linear or non linear?

Linear

63

x: 0 3 7 12

y:25 20 15 10

is this table linear or non linear? If so explain

non linear, because the x has is not a constant 

63

does the equation represent a linear or non linear?

y=x+5

Linear

63

Is the equation a linear or non linear? Explain

y=1-x2

Nonlinear because of the exponent

64

Is the graph linear or non linear

Non linear due to the line being curved and not straight

64

Which graph is linear

Second one is linear

64

IS this linear or non linear if so explain why

Non linear, because its no a striaght line and its curved

64


Which equations represent nonlinear functions?

5x+3y=4

y=3/x2

y=7/x2

y=x2+4

y=3/x2

y=7/x2

y=x2+4

are the non linear equations

64

Which equations represent linear functions? Why?

2x+3y=1

y=-9/x2

y=-5/x2

y=x2+7

2x+3y=1 is linear because its the only one without a exponent

65

Analyze this graph

It Increases are at a constant rapidly then stays at a constant then decreases at a constant rate

65

explain this graph

Increases Rapidly at a constant then decreases at a constant slowly then stays at a constant

65

analyze the graph

increases at a greater rate at a constant then stay at a constant the decreases at a constant then decreases at a constant then stay at a constant then decrease slowly at a constant

65


Increases at a constant rate then increases rapidly then stays at a constant then increases slowly at a constant the decreases slowly

65


increases rapidly then stays at a constant then increases slowly at a constant then stays at a constant the decreases slowly at a constant then stays at a constant then INCREASES Rapidly then stay at a constant4 then increases a little
