O f(x) has a local minimum at x = –
In the interval -3 < x < 3 the function f(x) has its minimum at x
= 3.
O f (x) has extrema at x =
3
In the interval -2 < x < 2 the function f(x) has both its minimum and local
minimum at x =
O In the interval -3 < x < 2 the function f(x) has both its maximum and local
5
maximum at x =
O f (x) has one inflexion point at x = 1.
