Please answer as soon as possible. Thanks

The Laplace transform of e\" is [em'] : 1 . If the Laptace transform of t) is F(s) and 1mm is the unit step function, a shifttheorem teLls us that [f(t 7 mun 7 b)] : e'b'Fu). From this SG 4 we can deduce that the inverse transform of F(s) : e"( 2) is: s _ O 4 mt me2H O 4 mt 2).;' O 4 mt 1).:21 O 4 an 7 1M\")
