    well, the independent variable defines the domian; so its going to be at least an x>= option

    D starts with a "y" so im going to go with a NO for that one

    the x >= 2500 seems a bit outrageous to me, since x represents months owned.

    B starts with a y ... which is not even defined in the equation. My gut says A
