The impulse response of a system is h(t) = t u(t). For an input u(t - 1), the output is

$${{{t^2}} \over 2}u\left( t \right)$$

$${{t\left( {t - 1} \right)} \over 2}u\left( {t - 1} \right)$$

$${{{{\left( {t - 1} \right)}^2}} \over 2}u\left( {t - 1} \right)\,$$

$${{{t^2} - 1} \over 2}u\left( {t - 1} \right)$$
