    How about you have a go, show us what your work, then explain why you're sure the book's answers are wrong?

    No.

    For no. 3 for example, the translation vector is [2,0] which means y=f(x) \mapsto y=f(x-2)

    Plugging x=3 then gives y=f(1)=1

    That means 3x gets mapped onto 3(x-b) since x \mapsto (x-b) from that translation.

    Now since 3x-3=3(x-b), you can easily find b if it's not obvious from inspection.
