Definition of a function is that y can only have 1 value for a given value of x.  Look at the values in the first problem: do you have any repeated values of x, with different values of y?  If so, it is not a function.  Look at the second problem: are there any repeated values of x, with different values of y?  If so, it is not a function.

Another way of thinking about this: if you would have to draw a perfectly vertical straight line to connect two points on the graph, it is not a function.
