  2. B \(2\)
  3. C \(\frac{{16}}{5}\)
  4. D \(\frac{{10}}{3}\)
Verified Solution

Answer & Solution

Correct Answer

(B) \(2\)

Step-by-step Solution

Detailed explanation

Since, \(g(x)\) is differentiable \( \Rightarrow g\left( x \right)\) must be continuous. \(\therefore g\left( x \right) = \left\{ {\begin{array}{*{20}{c}} {k\sqrt {k + 1} \,\,\,,\,\,\,\,0 \le x \le 3}\\ {mx + 2\,\,\,\,\,,\,\,\,\,3 < x \le 5} \end{array}} \right.\) At…
