$f^{'} (x) = 6 (x - 1) (x - 6)$

Local maxima at $x = 1$
Local minima at $x = 6$

f′(x)=6(x−1)(x−6) Local maxima at x=1 Local minima at x=6

Q. Function $f (x) = 2 x^{3} - 21 x^{2} + 36 x - 20$ has local minima at $x =$

$f^{'} (x) = 6 (x - 1) (x - 6)$

Local maxima at $x = 1$
Local minima at $x = 6$
