Let \( f(x)=\frac{x-1}{x^{2}} \), then which of the following is correct?
(a) \( f(x) \) has minima but no maxima
(b) \( f(x) \) increases in the interval \( (0,2) \) and decreases in the interval \( (-\infty, 0) \cup(2, \infty) \)
(c) \( f(x) \) can come down in \( (-\infty, 0) \cup(2,3) \)
(d) \( x=3 \) is the point of inflection
