Answer 1

Post your question in the opening post. It will give you a quicker response next time.

Answer 2

For part Question #1 you are given values for the "x" axis and then given values on the "y" axis.

One way of representing this is in ordered pair form. Here is an example:

\[x = ( 1, 2, 3) \]\[ y = (4, 5, 6)\]

\[\left\{ (1,4) , (2,5), (3,6) \right\}\]

But be CAREFUL, the ordered pairs are mixed up in question #1 in the answer, so choose carefully.

For Question #2 this link will provide you with the information you'll need to find the definition of a relation and a function:
