Best ResponseYou've already chosen the best response.1first coordinate of the vertex of \(y=ax^2+bx+c\) is always \(\frac{b}{2a}\) in your case \(a=3\) and \(b=24\) what do you get ?

Best ResponseYou've already chosen the best response.1what i meant was "what do you get for \[\frac{b}{2a}\]when you replace \(a\) by \(3\) and \(b\) by \(24\) and do the arithmetic
