Evaluate the limit, or state that the limit does not exist
4n-6n/10n

limit  is -1/5  if  you mean  (4n - 6n)/10n

else it is infinity  if you mean   4n  -  (6n/10n)

Step-by-step explanation:

Let me guess you mean the expression  (4n - 6n) /10n  with parentheses?

if so then this expression becomes   -2n / 10n  =  -1/5

take good notes.

do your homework.

use mnemonics and other tricks.

note: the best i know.

step-by-step explanation:

to find if any function is an inverse of the other, put the first equation in as x in the next one. then simplify and solve. if at the end you get the statement y = x, then it is an inverse. if you get anything else, it is not.
