You can put this solution on YOUR website!
Answers:
1) notice that the exponent is -2, an even number so it is symmetric about y axis
see graph below:

2)the vertex is infinity, when x approaches 0, approaches infinity
3)If you move the graph of one unit to downwards, you get the
graph of
see graph below
-- red; -- green

4) I am not sure if your question is a valid one or not. Basically these two have nothing to do with each other. See graph below.
