Final answer:
The limit of the function as t approaches 0 is undefined.
Step-by-step explanation:
To find the limit of the function lim t→0 3et - 3 t , 1 t - 1 t , 2 1 t, we can simplify it as follows:
lim t→0
=
= 3 - 3
= 0

=
=

= undefined

=

=

So, the limit of the function as t approaches 0 is undefined.
