So... im really stuck and my teacher says she is too busy to help me!
Here goes... functions.
f(x)= 3-x and G(x)= 3/x, X does not equal 0
a Find p(x) where p(x)= f(g(x))
b If q(x)= 3/3-x, x does not equal 3, find p(q(x)) in it's simplest form

Also... recurrence relations.
Two sequences are generated by the recurrence realations un+1= aun + 10 and vn+1= a^2vn + 16
The two sequences approach the same limit as n tends to infinity.
Determine the value of a and evaluate the limit.

Hope someone can understand this. Good luck x

So my homework on this topic is due after the holidays and i am really struggling! Can anyone help?

1. Find (x squared -2)(x squared +2)/ x squared dx


2. calculate the shaded area enclosed between the parabolas with equations y= 1+10x-2x squared ans y= 1+5x-x squared. I ended up with 20.8.


3. calculate the shaded area enclosed between the curve y= (x+1)(x-1)(x-3) and the line y= 5x-5.


Hope this is legible.
