Everything looks fine to me until 9.

For 9) :
Remember, $(f \circ g)(x)=f(g(x))$

This means that it equals $f(t)$ where $t=g(x)$

$f(t)=-t+5=-g(x)+5=-(x^2+2x+8)+5$

For 10) :
I think you have a typo (?) when you try -y=|x|+3
It makes y=-|x|-3, not -|x|+3

Good job =)

3. wow that was quick. Yes I think it was a typo. Thanks for the help on 9.
