Let f(x) = 5-4(x-2)^2/3 . Then at x=2, the function f(x)
a) Attains a minimum value
b) Attains a maximum value
c) neither
d)is undefines
Firstly, The function is not differentiable at $x=2$, So there is no question of maxima minima .
Also if I try to find the extremum points other than $x=2$ then also , there is no such points, as $f '(x) \ne 0$ for all $x$.
