Question

some calculus help

Answer 1

These problems involve the so-called "limit laws." Mind looking those up?
Here's an example:

"Find the limit (as x approaches c) of 4f(x)."
The relevant limit law states that "the limit as x approaches c of Df(x) IS D*the limit as x approaches c of f(X)." In other words, merely move the constant coefficient D outside of the limit, find the limit, then muliply that limit by D.

Since lim f(x) as x approaches c is given, and is 3/2,
the lim of 4f(x) as s approaches c is 4(3/2) =6.
