List-I (Function)	List-II (Fourier Transforms)
a. $$\exp \left( { - \alpha t} \right)u\left( t \right),\,\alpha > 0$$	1. $$\frac{1}{{{{\left( {\alpha + j2\pi f} \right)}^2}}}$$
b. $$\exp \left( { - \alpha \left| t \right|} \right),\,\alpha > 0$$	2. $$\frac{1}{{\alpha + j2\pi f}}$$
c. $${\text{texp}}\left( { - \alpha t} \right)u\left( t \right),\,\alpha > 0$$	3. $$\delta \left( {f - \frac{\alpha }{{{t_0}}}} \right)$$
d. $$\exp \left( {j2\pi \alpha t/{t_0}} \right)$$	4. $$\frac{{2\alpha }}{{{\alpha ^2} + {{\left( {2\pi f} \right)}^2}}}$$
