Key Features of Graphs
Domain & Range
100

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

What is the domain?

100

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

100

The y-intercept of the graph.

What is (0, 4)?

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

What is Yes?

200

The shaded region is increasing, decreasing, or constant.


Decreasing Interval

200

Find RANGE:


[-1, oo)

300

What is a discrete domain?

A domain which is made of separate points and can be listed

300

The mapping diagram shows a function or not.

What is No, not a function?

300

What is the range for this graph?

[-3,6]

300

Find DOMAIN:


all real numbers

(neg infinity, pos infinity)

400

How do you determine if a GRAPH is a function or not?

What is the Vertical Line Test?

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)?
