$1\mathrm{.}4$ Two functions representing the running time of a program, derived from the simplified mode, are given as follows:

$F_1(n)=n^2+9n+1$ and

$F_2(n)=7n+5.$

Use the big Oh properties to compute the asymptotic running time of the following:

$1\mathrm{.}4\mathrm{.}1F_1+F_2$

$1\mathrm{.}4\mathrm{.}2,F_1**F_2$

$1\mathrm{.}4\mathrm{.}1.$

$1\mathrm{.}4\mathrm{.}2$
