f(x)=x^2 + 1000 and O(x^2)

Your subject line says "prove it to me", which presumably means that you're needing to prove something, or are asking for something to be explained to you. However, you have posted only two cryptic lines. What, exactly, are you asking? Please use complete sentences. Thank you!

I wanted to know the big-O notation. How can I find the constant actually...because f(x)<=C(g(x))...then, the constant should be any number that held the constant. What is the relation between the graph of big-O notation and the constant?
