Best ResponseYou've already chosen the best response.1since you know it goes through \((5,6.3)\) replace \(x\) by \(5\), set the result equal to \(6.3\) and solve for \(a\)

Best ResponseYou've already chosen the best response.1i am not sure, however, how you know it goes through that point, because it doesn't really look like it

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
