Um... It's kind of slightly impossible for us to know if you're "on the right track" when we have no idea what you'd tried. :shock:
Please reply with a clear listing of everything you have tried so far, including the exact wording of the exercise and a definition of the "star" operator you are using. Thank you!
Eliz.
P.S. The "star" operator usually means multiplication, so "f*g" would mean (f(x))(g(x)), rather than, say, f(g(x)).
