i If two roots of f(x)are equal to k where k belongs to (0,4)
ii If two roots of f(x)are equal to k where k belongs to (-4,0)
iii If f(x) = 0 has 3 distinct real roots the number of such value of k is 3
iv If k belongs to N, f(x) = 0 has exactly one real root.

```										I had mistaken in writing the question the question is

Consider the functionx f(x) = x3-6x2+9x+k,where k is an integer
i If two roots of f(x)are equal  where k belongs to (0,4)
ii If two roots of f(x)are equal  where k belongs to (-4,0)
iii If f(x) = 0 has 3 distinct real roots the number of such value of k is 3
iv If k belongs to N, f(x) = 0 has exactly one real root.
