Problem 38
Use the operational properties and a known Fourier transform to compute the Fourier transform of the given function: $$ f(x)=x^{2} e^{-|x|} $$
Problem 44
In Exercises \(29-46\), find the Fourier transform of the given function. To simplify your computations, use known transforms and operational properties. \(f(x)=e^{-2}\) if \(|x|<1\) and 0 otherwise.
