Best ResponseYou've already chosen the best response.1satellite confused me at first when in his 2nd post he typed a instead of x. he made a human error which we all can make sometimes.

Best ResponseYou've already chosen the best response.1this can be dome in similar way to the first curve there are zeros at =4 and 2 and at x=0 with duplicity 2
