Find the Convolution Y(t) of X(t) and H(t); That Is $\text { find } y ( t ) = h ( t ) ^ { * } x ( t )$

Find the convolution y(t) of x(t) and h(t); that is, $\text { find } y ( t ) = h ( t ) ^ { * } x ( t )$ $$x ( t ) = \left\{ \begin{array} { c c } 3 , & 0 \leq t < 7 \\0 , & \text { otherwise }\end{array} , \quad h ( t ) = \left\{ \begin{array} { c c } 2 , & 0 \leq t < 3 \\0 , & \text { otherwise }\end{array} \right. \right.$$
