Domain, Range
   2   ,   4
   3   ,   9
  -2   ,   4
  -3   ,   9


Umm..  it's f(x)=x2, or y=x2; whichever notation you're used to.
Look;
22=4
32=9
(-2)2=4
(-3)2=4

The mental process went so;
I first noticed that both positives and negatives yield positive numbers, so it
must have been a parabola or xEven number with possible
complications.

Then I noticed that 2 is 4, and -2 is 4, so it was obvious to me that the
function was x2.  If you have any questions/concerns IM or email me.
