Yes!

assuming it does

the first question says f(f(x)) = 4x + 3
find f(x)

let f(x) =ax + b
carry the composition
find the composition and hence f(x)

there are too many different questions in terms of techniques for someone to run through all of them

the second one asks you to find the domain of g (as wide as allowable over the reals)
g is a composition of f
find it
then once you see the answer you can consider the domain
in radicals the argument cannot be negative for instance

Someone who could not read "show your working" is unlikely to be able to decipher that Tee!
