5. GAMES Some young people are playing a game
where a wooden plank is used as a target. It is marked
off into 6 equal parts. A value is written in each
section to represent the score earned if the dart lands
in that section. Let x denote the horizontal position of
a dart on the board, where the center of the board is
the origin. Negative values correspond to the left half
of the dart board, and positive values correspond to
the right half. A player's score depends on the
distance of the dart from the origin.
