Mathematics - Continuity - Differentiability Question with Solution | TestHub

b) $f(x)$ is count at $\mathrm{n}=1$

a) $g\left(1^{+}\right)=0,g\left(1^{+}\right)=1\Rightarrow g(x)$ is discontinuous at $\mathrm{n}=1$

c) $\begin{array}{rlc}h\left(1^{+}\right)& =1h\left(1^{-}\right)& =0\end{array}\}\Rightarrow h(x)$ is discontinuous at $\mathrm{n}=1$

d) $L.L\ne RL\Rightarrow \varphi (x)$ is discontinuous at $\mathrm{n}=1$
