title: Expressing (x^3)/1000 - 100*x^2 - 100*x + 3 in big theta notation
body: <p>Hello can somebody help me in expressing <code>(x^3)/1000 - 100*x^2 - 100*x + 3</code> in big theta notation. It looks like of <code>x^3</code> to me, but obviously at <code>x = 0</code> obviously this polynomial gives a value of 3. Multiplying <code>x^3</code> by any constant won't help at all. Is there a standard way to approach such kind of problem?</p>
