Step-by-step explanation:

To figure out whether a graph is a function, you need to use the line test.  The line test is where you pass a vertical line over the graph.  If the vertical line crosses the graph more than once, the graph is not a function.  You can use your pencil as a vertical line.

Graph 1 is not a function because the vertical line will cross the graph twice.

Graph 2 is a function because the vertical does not cross the graph twice.

Graph 3 is not a function because the vertical line will cross the graph twice.

3/20

Step-by-step explanation:

We have 3 sections.

So the entire spinner is divided into  sections

Red= 11/20

Blue= 6/20

Since we only have 3 sections(red, blue, green) we can add red and blue, and subtract 1 or 20/20.

11/20 + 6/20   11 + 6/20  17/20

Subtract:

20/20 - 17/20 = 3/20

So the probability that the arrow landing on a green-colored section is 3/20
