Solución

Ha introducido [src]
     x
|x|*e 
$$e^{x} \left|{x}\right|$$
|x|*exp(x)
Primera derivada [src]
     x    x        
|x|*e  + e *sign(x)
$$e^{x} \left|{x}\right| + e^{x} \operatorname{sign}{\left(x \right)}$$
Segunda derivada [src]
                                     x
(2*DiracDelta(x) + 2*sign(x) + |x|)*e 
$$\left(\left|{x}\right| + 2 \delta\left(x\right) + 2 \operatorname{sign}{\left(x \right)}\right) e^{x}$$
Tercera derivada [src]
                                                          x
(2*DiracDelta(x, 1) + 3*sign(x) + 6*DiracDelta(x) + |x|)*e 
$$\left(\left|{x}\right| + 6 \delta\left(x\right) + 2 \delta^{\left( 1 \right)}\left( x \right) + 3 \operatorname{sign}{\left(x \right)}\right) e^{x}$$
