Best ResponseYou've already chosen the best response.4how is defined: \[\Large \max \left( {f\left( x \right),g\left( x \right)} \right)\]?

Best ResponseYou've already chosen the best response.4we can write this: \[\max \left( {f\left( x \right),g\left( x \right)} \right) = \frac{1}{2}\left\{ {f\left( x \right) + g\left( x \right) + \left {f\left( x \right)  g\left( x \right)} \right} \right\}\]
