Why the lack of the Modulus sign in 7?
Also I got +4 for question 7 at the end.
Otherwise ye - everything stacks up in place. Good work!!!

the conditions given in the question stated , which makes both the moduli always positive
If you left them there, you'd probably lose a mark for not reading the question.
Also, yeah, there should be a +4 on the end. I'll edit this.

because it was a simple drawing!
I'm not going to TeX up a graph for a few straight lines!
Asymptotes were , intercepts were .
etc. etc.
