Answer :
Unfortunately, Serena is not correct. She has apparently lost sight of
most of the world of negative numbers.
In fact, if 'x' is ANY number less than negative 1/3, then 3x+1 is less than zero.
There are a huge load of numbers that qualify.

Serena is wrong. She has completely ignored negative numbers.
With negative numbers, it is possible to have an answer that is less than zero.
For example, x=-2
3(-2)+1= -5
which is not > than 0.
