Match each expression on the left with an equivalent sum on the right, using the following functions.

$\displaystyle{f{{\left({x}\right)}}}={{x}}^{{2}}-{8}{x}+{4}\usepackage{cmbright}\Huge\$

$\displaystyle{g{{\left({x}\right)}}}={{x}}^{{3}}+{8}{x}+{4}\usepackage{cmbright}\Huge\$

$\displaystyle{h}{\left({x}\right)}=-{{x}}^{{3}}-{{x}}^{{2}}+{8}{x}-{4}\usepackage{cmbright}\Huge\$

Some answer choices on the right will not be used.
