    divide the coefficient of t by 2 6 / 2 = 3 so we have f(x) = (t + 3)^2 - 9 - 20 = (t + 3)^2 - 29

    - thats vertex form

    ok 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)

    the coefficient od t^2 is positive so that makes the vertex a minimum.

    the axis of symmetry is the vertical line going through the point (-3,-29) can you tell me the equation of that line?

    yes 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
