A function will not have any repeating x values....it can have repeating y values, but all the x values have to be different for it to be a function.
A is a function because all the x values are a different number
B is not a function because u have repeating x values...u have repeating 4's and repeating 9's
The two inequalities can be rewritten as

The solution is composed by every point below the graph of the line
, and above the horizontal line 
To draw the line
we can build a little table (only 2 points are required):

So, if you draw the points (0,2) and (1, -2) and connect them, you'll have your line.
To draw the line
, simply pick any point with y coordinate -2, for example (0, -2), and draw a horizontal line.
Choose the above/below areas as specified above to solve the system.
