Maths difficulties

Hi,
First,my english isn't as good,but hope you'll understand what i tried to write.
I've been unable to solve these for 2 long weeks:
-Give the domain and range for the rational function.Use interval notation
f(x)=1/(x-1)square+3
-Give the equationsof the vertical and horizontal asymptotes of the given equation's graph:
Y=1/(x-1)square+3
-Answer the question
How can the graph of f(x)=1/x-4+13 be obtained from the graph of Y=1/x
-Find the indicated asymptote(s)
   the vertical asymptote(s) of h(x)=x-6/xsquare-25
   the horizontal asymptote(s)of h(x)=6xsquare-8x-7/7xsquare-7x+6
   the oblique asymptote(s) of f(x)=xsquare-5x+6/x+5
-Solve hte equation and the inequality.
x+5/x-6=0  ;  x+5/x-6<or=0
-Solve the equation 
 root3x+1=3+rootx-4
-If f is one-to-one,find an equation for its inverse:f(x)=xcube-7
Do HELP me please,otherwise the consequencies will be damaging for me.
THANKS
