Use the functions:

f(x)=\displaystyle {f{{\left({x}\right)}}}= −2x+3\displaystyle -{2}{x}+{3}

g(x)=\displaystyle {g{{\left({x}\right)}}}= 6x−4\displaystyle {6}{x}-{4}

to find the following values, if they exist.

(i)  (f+g)(−2)=\displaystyle {\left({f}+{g}\right)}{\left(-{2}\right)}=   

(ii)  (f−g)(1)=\displaystyle {\left({f}-{g}\right)}{\left({1}\right)}=   

(iii)  (f⋅g)(6)=\displaystyle {\left({f}\cdot{g}\right)}{\left({6}\right)}=   

(iv)  (fg)(−7)=\displaystyle {\left(\frac{{f}}{{g}}\right)}{\left(-{7}\right)}=
