Hello Professor Hovasapian,

In example II, I just confused why the function is continuous in the interval (-?, 14/4]. We just got the answer that the function is continuous at x=2 ONLY right?

Also, if f(x) and g(x) are both continuous, is f-g also continuous?

And for example VI, from my point of view, since the f(4) is positive and f(6) is negative, definitely f(x) would have only one real root (f(x) would pass through x-axis only ONCE :). I don't understand why there are more than one root between this interval?

Thank you for your time to answer my question.

Sincerely,

Acme

Professor Raffi Hovasapian,

Why f(a) cannot equal to f(b) in intermediate value theorem?

Thanks for the answer!
