there’s no ms but the exam solutions says that it’s
If they said translate f(x) into f(x+2) ??

for part b
If it’s a translation in the x axis… wouldn’t it be -2 (cos u do the opp of what’s in the brackets

That rule of doing the opposite of whatever function is in the brackets only applies when you're actually doing the transformation i.e., shifting it left two units if it's (x+2). But, we just need the equation, we're not transforming anything - so you sub in (x+2) into your function, f(x).

(x+2+3)^2 (x-1+2) =

(x+5)^2 (x+1)

Hope this makes sense.
