Continuity at c needs which three quantities to be equal?
Af(c), f'(c) and f''(c)
Bleft limit, f(c) and f(0)
Cleft limit, right limit and f(c)
Df(c - 1), f(c) and f(c + 1)
Answer & Solution
Correct answer: C. left limit, right limit and f(c)
The two one-sided limits must agree, giving the limit, and that common value must equal f(c).
