JEE Math Practice Question
If m is the minimum value of k for which the function f(x) = x$$\sqrt {kx - {x^2}} $$ is increasing in the interval [0,3] and M is the maximum value of f in [0, 3] when k = m, then the ordered pair (m, M) is equal to :
- A.$$\left( {5,3\sqrt 6 } \right)$$
- B.$$\left( {4,3\sqrt 3 } \right)$$
- C.$$\left( {4,3\sqrt 2 } \right)$$
- D.$$\left( {3,3\sqrt 3 } \right)$$
