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.

300

The mapping diagram shows a function or not.

What is No, not a function?

300

Based on the graph of the function, what is f(4)?

f(4) = -2

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?

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)?
