How would you "remove the discontinuity" of f? In other words, how would you define
f(5)
in order to make f continuous at 5?
f(x) =
x2 − 4x − 5
x − 5

Please use your own mind too and calculate limit. Don't depend completely on others otherwise you will not ever be able to do anything by on your own without the help of others. 

Thanks.
