1. Given \(f\left( x \right) = 6x + 2\) and \(g\left( x \right) = 10 - 7x\) compute each of the following.

\(\left( {f - g} \right)\left( 2 \right)\)

\(\left( {g - f} \right)\left( 2 \right)\)

\(f\space g\)

\(\displaystyle \left( {\frac{f}{g}} \right)\left( x \right)\)

Answer

-18

\[f\space g = f\left( x \right)g\left( x \right) = \left( {6x + 2} \right)\left( {10 - 7x} \right) = {{ - 42{x^2} + 46x + 20}}\]

\(\left( {\frac{f}{g}} \right)\left( x \right) = \frac{{f\left( x \right)}}{{g\left( x \right)}} = {{\frac{{6x + 2}}{{10 - 7x}}}}\)
