    Question Help!!! (Yes or No Q)

    Is it No, F is not continuous function of r? help help! well, since i think that there's a space between this fuction...it's no?

    i also checked these 2 sites: @ yahoo

    Calculus + Continuous Functions? - Yahoo! Answers

    Limit continuity concept question? - Yahoo! Answers

    can't really decide since it's 50% each. but i'm going for the no since there seems to be a gap! help

    Draw the graph. There is no jump (or gap as you call it). It should be quite clear that the two parts of the graph join at r = R. F is continuous.

    Note 1: The domain for the first part of the rule is wrong. It should be 0 \leq r < R.

    Note 2: The function is NOT differentiable at r = R.
