BAD GUESS
¦ In a CALC o
p
eration,
y
ou s
p
ecified a Guess that is not
b

p
ecified a
g
uess that is not between lowe
r
and uppe
r
.
¦ Your guess and several points around it are undefined.
Examine a graph of the function. If the equation has a solution,
change the bounds and/or the initial guess.
