Notice that
LEFT
and RIGHT are relatively far apart. This
indicates
that the
answer
is probably not a good solution to the equatiorl,
and
demonstrates
the importance of viewing
LEFT
and R/GHT
for
a case
I
solution
if
you have any doubt about the
answer.
Examining the
graph of the function
(see
figure B-5) shows how the Solver arrived
at
the
answer.
When the iterative
process
produced
the estimate
X
-
10,
the Solver determined that two neighboring
estimates
yield
values
of
f@
with
opposite
signs.

The
