h(x)=x-1; g(x)=5x-2
Am I a function?
What's my function?
Domain and Range
100

This word is used to describe the set of all inputs for a function.

What is the domain?

100

Find h(3)

What is 2?

100

What is No, not a function?  It does not pass the vertical line test.

100

Am I a linear function?

No, I am not made of a LINE

100

Find the DOMAIN:

{(-2, 4), (3, 2), (2, 10)}

What is {-2, 3, 2}?

200

This word is used to describe the set of all outputs of a function.

What is the range?

200

Find g(4) 

What is 18?

200

What is Yes, a function?

200

Am I a linear function?


yes, it is a linear function --- it is made of a (straight) line. 

200

Find the RANGE:

{(-2, 4), (3, 2), (2, 10)}

What is {2, 4, 10}?

300

This word describes a relation that pairs each x value with only one y value.

What is a function?

300

What is x if h(x) = 5

What is 6?

300

Is this a function and why?

What is no, because x's repeat at 8?

300

Am I a linear function?


No. I am not made of a straight line.

300

Is the following a function?

x        1.       3           5           7

y        2.        3          4           5

Yes, each input has exactly one output.

400

This word describes a relationship between two sets of numbers.

What is a relation?

400

What is x if g(x) = 18

What is 4 ? 

400

Does the following table represent a function?
x      y
1      2
2      5
6      2
2      9
5      1

What is No, because the input (x) of 2 has two different outputs (y)?


400

Does the following table represent a linear function?
x      y
1      2
2      5
6      2
2      9
5      1

No, there is not a constant rate of change 


(also it is NOT a function, so it can be a LINEAR FUNCTION)

400


Is the following a linear function?

x        1.       3           5           7

y        2.        3          4           5

Yes,  it has a constant rate of change.

500

We use "x" to describe the input, what do we use to describe the output? 

What is Y?

500

What is h(-3) 

What is -4?

500

Is this a function?

 No, it fails the vertical line test

500

Would this graph be consider discrete or continuous?

Discrete --- it is made up of a series of points --- not the numbers in between.

500

Is the following a linear function?


x         3        6        9           12

y          5        7        10        12

 No, there is not a constant rate of change
