If you derive g(f(x)), you end up getting gf(x) = x . I still do not understand why this is not supposed to be possible. Could you share a pic of what the mark scheme says?

No mark scheme out yet, check your conversations.

I got it. g(x) is defined for x > 2. When x=3, f(3)=10. but g(x) is only defined for 2 < x <4 so this is not valid.

Ah okay, so you would write this as: range of f(x) is outside the domain of g(x) I guess. Thanks.

Since CD lies in the same line as BC then it must be an integer multiple of the unit vector of BC (The integer will be the magnitude of CD).

In this case we don't know if CD is in the same direction as BC or the opposite, so it can either be a positive or a negative integer multiple of the unit vector.

CD = +/- (CD magnitude)(unit vector of BC)

OD = +/- (CD magnitude)(unit vector of BC) +OC

Thankyou!
