Question

Which one or ones of the following statements is/are true?

If the line y = 2 is a horizontal asymptote of y = f(x), then f is not defined at y = 2.
If f(5) > 0 and f(6) < 0, then there exists a number c between 5 and 6 such that f(c) = 0.
If f is continuous at 2 and f(2)=8 and f(4)=3, then lim ->2 f(4x^2-14)=8
All statements are true.
