Best ResponseYou've already chosen the best response.0now, please replace x with 2, what do you get? \[\begin{gathered} \left( {f + g} \right)\left( x \right) = 2{x^2} + 4x  2 \hfill \\ \hfill \\ \left( {f + g} \right)\left( 2 \right) = 2 \times {2^2} + 4 \times 2  2 = ...? \hfill \\ \end{gathered} \]
