Answer:
maximum : [tex] ϵ -29 [/tex] a number infinitesimally larger than -29, or -28 if you prefer integers
minimum : [tex] -\infin [/tex]
negative infinity
Explanation:
if t + 31 < 2
than t + 31 - 31 < 2 - 31
t < -29
[tex] -\infin < t \:< - 29[/tex]
any number less than -29
ϵ just means infinitesimal small quantity denoted as [tex] \pm \frac{1}{\infin} [/tex]
