    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 =)
