Question

What are the minimum and maximum values of t for which ſt + 31 < 2?

Answer 1

maximum :
`ϵ -29` a number infinitesimally larger than -29, or -28 if you prefer integers

minimum :
`-\infin`

negative infinity

Step-by-step explanation:

if t + 31 < 2

than t + 31 - 31 < 2 - 31

t < -29

`-\infin < t \:< - 29`

any number less than -29

ϵ just means infinitesimal small quantity denoted as
`\pm (1)/(\infin)`
