Answer:
Part A - Represents a function
Part B - Doesn't represent a function.
Step-by-step explanation:
A set is just a list of numbers to check. The question is asking you based on the set...
(-5, 8)
(-6, 2)
(-2, -6)
(-1, 8)
(4,6)
if it is a valid function.
At NO point should a function have multiple x values. This fails the <em>Vertical Line Test</em> if visualized on a graph.
For Part A, there are no duplicate x values, meaning this function is valid.
For Part B, there is a duplicate x value - (2,9) & (2,4). Because of this, immediately the function is invalid. There can not be any duplicate x values in a valid function, <u>PERIOD</u>. If graphed, it fails the vertical line test.

There isn't a specific number so i'll just list all of them.
2 : 100 millions
3 : 10 millions
4 : millions
5 : 100 thousands
0 : 10 thousands
0 : thousands
4 : hundreds
5 : tens
0 : ones
Answer:
$2.48
Step-by-step explanation:

7.44/3=2.48
So $2.48
