    the constant under the radical gives horizontal shift, so it's associated with the domain. The constant added/subtracted gives vertical shift so it goes with the range. → b has to be under the radical and a outside.

    That's got a domain of all real numbers

    well if a function isn't a fraction there is no restriction at all.

    I think the restriction comes from the domain of the square root.

    But there shouldn't be a description on a cube root

    I think it's got to be the square root one. You could always pick numbers for a and b and graph the functions to see what matches
