4. Find the convolution of $f(t)=\left\{\begin{array}{11}\frac{3}{2} t, & 0 \leqt \leq 3 \ 0, &
\text { otherwise }\end{array}\right.$ and Sg(t)=\left\{\begin{array}{i1}4, & -i leg i \leg 3' e,
& \text { otherwise }\end{array}\right. $
Answer:
$$
f* g=\left\{\begin{array}{11}
0 & t \leqslant-1 \
\frac{4}{3}(t+1)^[2} & -1<t \leqslant 2 W
12 & 2<t \leqslant 3 \
12-\frac{4}{3}(t-3)*(2} & 3<t \leqslant 6 \
O & t>6
\end{array}\right.
