F >= g function definition

  1. Apr 30, 2013 #1
    Here's something which always manages to throw me in doubt.

    When one defines a function f to be greater than or equal to (or strictly greater) some other function g,

    So f >= g / f > g over some interval [a,b] simply speaking.

    Does this mean that for any value x in [a,b] : f(x) >= g(x)?

    OR

    f(x) >= g(y) , for any x in [a,b] and for any y in [a,b] ?

    Any insight will be highly appreciated, I'd like to clear this issue once and for all.

    Thank you very much!
