Find the critical points, domain endpoints, and local extreme values for the function.
\[
y=x^{4 / 5}(x-3)
\]
From the critical point(s) and domain endpoint(s), what is/are the point(s) corresponding to local maxima? Select the correct choice below and, if necessary, fill in the answer box to complete your choice.
A. The point(s) corresponding to the local maxima is/are
\( \square \)
(Type an ordered pair. Use integers or decimals for any numbers in the expression. Round to the nearest thousandth as needed. Use a comma to, separate answers as needed.)
B. There are no points corresponding to local maxima.
