Best ResponseYou've already chosen the best response.0divide the coefficient of t by 2 6 / 2 = 3 so we have f(x) = (t + 3)^2  9  20 = (t + 3)^2  29

Best ResponseYou've already chosen the best response.0ok the general form for veretx is (x  a)^2 + b where (a,b) is the coordinates of the vertex so comparing with our result the vertex is at (3,29)

Best ResponseYou've already chosen the best response.0the coefficient od t^2 is positive so that makes the vertex a minimum.

Best ResponseYou've already chosen the best response.0the axis of symmetry is the vertical line going through the point (3,29) can you tell me the equation of that line?

Best ResponseYou've already chosen the best response.0yes you can work it out that way. but easier way is to note that vertex has t = 3 so axis of symmetry is t = 3
