Question 252405: how do I graph 
and 
how do I explain on a graph

You can put this solution on YOUR website! Here is the first equation:
Notice the variable in the denominator. We don't like these there and want to know where the function can't exist. Set the denominator not = 0 and solve. In this case, X not = 0. This gives us a vertical asymptote at x = 0.From here we create a table of values.
(X,Y): (-2,11.5), (-1, 13) (1,-.5) (2,2.5) (3,9) (4,16.5)
Notice the graph is a hyperbola.
Here is the second equation
Since there are no restrictions on X, we go right to a table of values.
(X,Y): (-3,10)(-2,4) (-1,0) (0,-2) (1,-2) (2,0) (3,4)
Notice this graph is a parabola.
Now I am not sure if you wanted to know where they crossed, if at all?
They would cross at
