## Rational Functions help?

a) Graph:
Code:
f(x) = 2x+3
-------
x+4
, labelling all zeroes, intercepts, asymptotes + give its domain and range

b) Now do the same for its inverse

c) Graph g(x)=
Code:
 x^3 - 8x
------------
(x+1)^2
, labelling all zeroes, intercepts, asymptotes.

Does it have an inverse? Why or why not?

Thanks/Rep for whoever helps!
