Points of discontinuties of the function $\text{⨍ }\left(\mathrm{x}\right)\text{=4x+7}\left[\mathrm{x}\right]\text{+2log}\left(1+\mathrm{x}\right)$ are

$\mathrm{f}\left(\mathrm{x}\right)=4\mathrm{x}+7\left[\mathrm{x}\right]+2\log (1+\mathrm{x})$

$\left[x\right]$ is discontinuous for all $\mathrm{ }\mathrm{x}\in \mathrm{z}$

$\log (1+\mathrm{x})$ is defined if $\left(1+\mathrm{x}\right)>0\Rightarrow \mathrm{x}>-1$

$\Rightarrow \mathrm{x}=0,\mathrm{x}=1,\mathrm{x}=\frac{-3}{2}$are points of Discontinuous

$\therefore$option (4) is correct
