Question

solomonzelman · Answer

$\large\color{blue}{ f(x)=3x-7       }$
$\large\color{red}{ g(x)=-2x-6   }$

$\large\color{slate}{ (\color{blue}{ f }\times \color{red}{ g })(x)=\color{blue}{ (3x-7) }\times \color{red}{ (-2x-6)}}$

solomonzelman · Answer

you can go ahead without expanding anything,

$\large\color{slate}{ (\color{blue}{ f }\times \color{red}{ g })(x)=\color{blue}{ (3x-7) }\times \color{red}{ (-2x-6)}}$

$\large\color{slate}{ (\color{blue}{ f }\times \color{red}{ g })(\color{green}{4})=\color{blue}{ (3\color{green}{(4)}-7) }\times \color{red}{ (-2\color{green}{(4)}-6)}}$
