Question

please help with functions

Answer 1

You have to join the dots in the order that the sequence tells you to. By coincidence, this happens to be left to right.

To test you draw a vertical line through the graph. If it only touches the original graph once then the relation is a function. If not then it is simply a relation.

Think you can do it now?

Answer 2

That's a right graph, is it a function or a relation now?
:P

Answer 3

Yep, nice work
