Answer 1

The graph is a function because when you use the vertical line test it does not hit more than one point at any given place on the line.

Hope this helped :)

Answer 2

You can take up a straight edge or a ruler and draw a straight line through the points, if the vertical line you drew intersects the graph more than once for any value of x then the graph is not the graph of a function. Hope it helps :)
