Let $r$ be a function defined on $0,-.$ Then the function $F$ defined by

$f(s)={\displaystyle \underset{0}{\overset{}{}}}{e}^{-st}f(t)dt$

is said to be the Laplace transform of $f.$ The domain of $F(x)$ is the set of walues of s for which the given improper integral converpes

Use the definition of a Laplace transform to find $(f(t)).($Write your answer as a function of s$.)$

$A+1=e^{-1}s\frac{in}{n}$

$r(n))>(-1$
