Determine the points in the interval \( (1,6) \) at which the function has a discontinuity. At each point of discontinuity, state the conditions in the continuity checklist that are violated.
1. \( f(a) \) is defined ( \( a \) is in the domain of \( f \) ).
2. \( \lim _{x \rightarrow a} f(x) \) exists.
3. \( \lim _{x \rightarrow a} f(x)=f(a) \) (the value of \( f \) equals the limit of \( f \) at \( a \) ).
\( f(x) \) is discontinuous at \( x=2,3,4 \).
(Use a comma to separate answers as needed.)
Select the correct choice and, if necessary, fill in the answer box to complete your choice.
\( \square \) A. The point(s) at \( x=\square \) violate(s) the first condition in the continuity checklist. \( \square \) (Use a comma to separate answers as needed.)
B. No point violates the first condition in the continuity checklist.
