Not too bad. Was that done with a finger or a stylus? (or something else?)

Thanks Sue! I'm using HandDraw with a cheap stylus. I did that while lying down writing vertically! It can only get better!
I administered this problem to my SAT group this am. Some solved the College Bd Problem of the Day but none got my problem. This is reasonable because
(a) grid-in not MC
(b) use of parameter k preventing use of graphing calc
(c) ?? Your turn
