Q472

Let \[x_1 ( t ) = \ array*20c 6& for 0 < t < 4 \\ 0& otherwise array . and x_2 ( t ) = u ( t - 2 )\] and y(t) = x1(t) * x2(t), then the value of y(4) is

Let {x_1}\left( t \right) = \left\{ {\begin{array}{*{20}{c}} 6&{{\text{for }}0 < t < 4} \\ 0&{{\text{otherwise}}} \end{array}} \right.{\text{and }}{x_2}\left( t \right) = u\left( {t - 2} \right)         and y(t) = x1(t) * x2(t), then the value of y(4) is
