What is the definition of a function?

Every input value has exactly one output value. 

(Answers may vary)

100

is the given function linear or nonlinear? Explain.



Linear because its a straight line that constantly increases.

Identify the domain and range of the following:

D: -2 < x < 4

R: -3 <= y <= 3

Find the domain and range of the following set:

{(9, 1) (-8, 0) (-1, 7) (0, 6) (-5, -7)}

D: {-8, -5, -1, 0, 9}

R: {-7, 0, 1, 6, 7}

What are the two ways you can determine if something is a function or not?

Vertical Line Test & Different x-values

200

is the given function linear or nonlinear? Explain.

Linear because the inputs and outputs both change at a constant rate. m=4/1 <-- constant rate

200

What is the domain and range of the graph?

Domain: 0 <= x < infinity 

Range: -2 <= y < infinity

200

Find the domain and range of the following set:

{(1, 1) (2, 0) (0, 3) (0, 6)}

D: {0, 1, 2}

R: {0, 1, 3, 6}

300

Determine whether the given relation is a function or not and explain your answer.


Not a function because it fails the vertical line test.

300

Is the given function linear or nonlinear? Explain.

Nonlinear because it does not have a constant rate. The y values change by 5,8,9, and 6.

300

What is the domain and range of the following?

Domain: -infinity < x < infinity

Range: -4 <= y < infinity

300

Find the domain and range of the following:

{(0, 1) (0, 2) (0, 0) (0, -2) (0, -8)}

D: {0}

R: {-8, -2, 0, 1, 2}

One of the tables below are a function the other isn't. Explain the difference between the two.
 

The first table is a function and the second isn't, x must always be different to be a function.

between x=1 and x=5

What the domain and range of the following?

D: -2 <= x <= 6      R: -6 <= y <= 2

400

What is the domain of the following? Think about what domain is...

{2, 3, 5, 7, 9}

Make up your own example of a table of values that is a function and another example that is not a function. Include at least 3 inputs and outputs each. 

*answers vary*

500

Is the table linear? Explain. 

Linear, because the constant rate is 2.

Identify the domain and range of the following graph.

Range: y=-2

Domain: -infinity < x < inifinity

500

What is the range of the following? Think about what range is...

{1, 3, 4, 5, 6}
