    Well you want to take x -> 3x -> 3x + 2. What is this in terms of g and h?

    [it's hard to give a hint here without writing down the answer]

    Notice that x \mapsto 3x+2 is very similar to g : x \mapsto x+2, except the input is 3x rather than x. Precisely, h(x)=3x therefore the function f : x \mapsto 3x+2 is...?

    Compose the functions and add a constant.

    Edit: might have read this wrong and you have to do it for each function.

    Take rdks advice.

    Yes I was in terms of g and h. So technically it’s trial and error? Also thanks for answering.

    So then this will be gh? Sorry this topic confuses me

    Indeed it will be! The function is gh(x) = 3x+2
