Answer 1

tell me anybody

Answer 2

Without writing a formal def. as I'm sure you have it in your book this is basically what continuity is....

Consider first only continuity at a single point
if the limit at a = f(a) then you have continuity at a

Now lets consider continuity over an interval
if an interval, S, is continuous then for every point s in S limit at s = f(s)

What is mean is an interval is continuous if every point in the interval is continuous.
