Continuity in an Interval
A function f(x) is said to be continuous in an interval I, if it is continuous at each point of I. then x can approach c both from the left and the right and so for f (x) to be continuous at c, we must have If the interval I is the closed interval [a,b], then x cannot approach a from the left and i..

Proof:
Since g is continuous at c, we have Again, f is continuous at g(c) and so Hence fog is continuous at ..

We have discussed earlier about right hand limit and left hand limit. Both these limits are called one sided limits. x approaches a from the right side and through values greater than a. For a function f(x), we say as left hand Limit, as x approaches a from the left and through the values less..

Let f(x) tend to a limit l 1 as x tends to a through values less than 'a', then l 1 is called the left hand limit which is symbolically written ..

I am Jessica from New York, I got excellent English tutors from Tutor Vista, who helped me lot to overcome my grammar mistakes, Thanks a lot...
I used to fail in my math class, after I joined Tutor Vista I am getting good grades in math, Thank you
We have a single tutor for 40 students in school, where as I have a personal tutor for myself with Tutor Vista, It's a great help -Joe
I asked a Math question in the chat box in tutorvista. I was amazed to see live response from the tutor who helped me with my questions. That was great. I joined their online regular tutoring so that I can get such help anytime. - Mary
