Find an antiderivative F(x)\displaystyle {F}{\left({x}\right)} of the function f(x)=4x2\displaystyle {f{{\left({x}\right)}}}=-\frac{{4}}{{{x}^{{2}}}} such that F(1)=2\displaystyle {F}{\left({1}\right)}=-{2}.

F(x)=\displaystyle {F}{\left({x}\right)}=  

Now, find a different antiderivative G(x)\displaystyle {G}{\left({x}\right)} of the function f(x)=4x2\displaystyle {f{{\left({x}\right)}}}=-\frac{{4}}{{{x}^{{2}}}} such that G(1)=7\displaystyle {G}{\left({1}\right)}=-{7}.

G(x)=\displaystyle {G}{\left({x}\right)}=
