MCQ
$Let\,\,f(x) = \left\{ {\begin{array}{*{20}{c}}
{{x^2} - a\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,;\,\,x < 3} \\
{b\sqrt {x - 2} + a\,\,\,\,\,\,\,\,\,\,\,;\,\,3 \leqslant x < 6.} \\
{2x + b\,\,\,\,\,\,\,\,\,\,\,\,\,\,\,;\,\,\,x \geqslant 6}
\end{array}} \right.$ If $f(x)$ is continuous $\forall x \in R$, then value of $\frac{f(1)-f(3)}{4}$
