**[SOLVED] Calculus Help with Limits (check my work please)**

Some problems, I just couldn't do on my own, but I've done some problems with answers provided here. Please check my work and show me how to do the problems I couldn't do. I would appreciate it.

Problem 1:

Lim

x--> 3^- (left side)

x--> 3^+ (right side)

x--> 3

Expression:

|x+3| / (x-3) <== absolute value expression

--------------------------

Problem 2:

lim x--> 3^-(left side)

f(x) , where

5x-7 if x is less than or equal to 3

and

x^2+1 if x is greater than 3

Answer: f(x) = 8 (I'm not sure if it is right. Correct me if I'm wrong)

---------------------------

Problem 3:

lim

x-->3

(x^2-2x-3)/(x^2-6x+9)

Answer: 1 (I'm not sure if it is right. Correct me if I'm wrong)

---------------------------

Problem 4:

lim

x--> 2^- (left side)

x--> 2^+ (right side)

(3x+1)/(x-2)

--------------------------

Problem 5:

lim

x-->3

(2x+6)/(x)

Answer: 4 (I couldn't figure it out whether it was 4 or 8.)
