If f$($t$)$ is defined for t $>=0,$ then its Laplace transform F$($s$),$ also denoted $$f$($s$)$ or $[$f$($t$)],$ is defined by F$($s$)=[$f$($t$)]=\backslash$infty e$$stf$($t$)$ dt$,0$ for values of s for which the improper integral converges. Apply the definition above to find the Laplace transform of the following function. $($Enter your answer in terms of s$.)$
