Find the derivative of each function.

f$($x$)=13$x$4-7$x$3+5$x$2+11$x$+75[2$ Marks$]$

f$($x$)=($x$3+2$x$2+4)($x$4-3)[3$ Marks$]$

f$($x$)=3$x$2-6$x$+74$x$-1[3$ Marks$]$

f$($x$)=(4$x$3-7$x$)7[2$ Marks$]$

$12=$y$3+$x$2[4$ Marks$]$

f$($x$)=156[1$ Marks$]$

f$($x$)=(1-3$x$)2($x$2-2)3[3$ Marks$]$

f$($x$)=(2$x$2+13$x$3+1)2[3$ Marks$]$

f$($x$)=(2$x$-3)(5-$x$)($x$2+2$x$-1)[4$ Marks$]$
