O-2 is a local minimum of f(x) at x = 1. -18 is a global and local minimum of f(x) at x = -3. 2 is a global and local maximum of f(x) at x= -1. -18 is a global minimum of f(x) at x=-3. 2 is a global maximum of f(x) at x=-1. O-2 is a local minimum of f(x) at x = 1. -18 is a global and local minimum of f(x) at x=-3. 2 is a global and local maximum of f(x) at x=-1.
