Consider the following function. f(x) = (2x)/(x − 4)

Describe the local behavior of the function.
f(x) is undefined at x = 4

As x approaches this value from the left side, f(x) approaches ?

As x approaches this value from the right side, f(x) approaches ?

Describe the end behavior of the function.
As x → ∞, f(x) →

and as
x → −∞, f(x) →

I’m really having a tough time understanding. The answers I think are right keep getting dismissed by the homework website... I would super appreciate the help and also how you got the answer!
