The graph of the function f(x)= ) = { 1 for 2n is less to equal to x is less or equal to 2n +1, 0 for 2n+1 is less or equal to x is less or equal to 2n+2 where n = (0,1,2,.....) is shown below. Its Laplace transform (s) is f(x) (a) 1+es S 1 () s(l+e=) (b) 1-e for 2n x 2n+1 for 2n +1x 2n+2 S 1 (d) s(1-e~) "boo 2 3 4 1 0 5
