JEE Math Practice Question
If the function. $$g\left( x \right) = \left\{ {\begin{matrix} {k\sqrt {x + 1} ,} & {0 \le x \le 3} \\ {m\,x + 2,} & {3 < x \le 5} \\ \end{matrix} } \right.$$ is differentiable, then the value of $$k+m$$ is :
- A.$${{10} \over 3}$$
- B.$$4$$
- C.$$2$$
- D.$${{16} \over 5}$$
