For example, there's a reference to a table, but you didn't copy the table. Also, it's not entirely clear whether f(x)=(x-1)^(1/2) or f(x)=x^(1/2)-1. And then in point 2 you redefine f(x) using cube roots, but normally a textbook or worksheet would use a different letter to avoid confusion, since we already used f(x) to mean something else.
Also the question "when will g(x)=x-1 be a function" doesn't seem to make much sense, since that is always a function, for all real x.
Would it be possible to take a picture of the problem and upload using, say, tinypic.com?
