Topology continuity

  1. Feb 24, 2009 #1
    Let F: X x Y -> Z. We say that F is continuous in each variable separately if for each y0 in Y, the map h: X-> Z defined by h(X)= F( x x y0) is continuous, and for each x0 in X, the map k: Y-> Z defined by k(y) =F(x0 x y) is continuous. Show that if F is continuous, then F is continuous in each variable separately.

    I'm not sure how to do this....

    if you guys would help me out that would be amazing!
    Thank You

    What is the definition of F being continuous?
