  1. Not sure what operation @ indicates.
    Now what all the ? signs are supposed to mean.

    Clearly the domain is the set of values of x for which f(x) is defined.

    There appears to be a change of definition in the domain. Is f(x) the same on both sides of that point?

    ow about using some more standard notation (x <= 2 or something), and some of your ideas on the solution? This surely cannot be totally foreign to you; your text must have solved similar problems.

    Review some of the related questions below. Your solution is probably clearly indicated in them.
