#2#

The question can be written as

#lim_(trarr0)(4t-2t)/t#

Simplify the numerator.

#lim_(trarr0)(2t)/t#

Notice that the #t# terms will cancel.

#lim_(trarr0)2=2#

The function should approach #2#. We can check a graph:

graph{(4x-2x)/x [-5.11, 5.99, -1.88, 3.67]}

Notice that #t=0# is undefined.
