axis y=-3[x^2-16/3 x+64/9-4-64/9 ]

axis

y = - 3 [x^{2} - \frac{16}{3} x + \frac{64}{9} - 4 - \frac{64}{9}]

x = \frac{8}{3}

Solution steps

y = - 3 [x^{2} - \frac{16}{3} x + \frac{64}{9} - 4 - \frac{64}{9}]

Rewrite

y = - 3 [x^{2} - \frac{16}{3} x + \frac{64}{9} - 4 - \frac{64}{9}]

in the standard form

4 (- \frac{1}{12}) (y - \frac{100}{3}) = (x - \frac{8}{3})^{2}

Therefore parabola properties are:

(h, k) = (\frac{8}{3}, \frac{100}{3}), p = - \frac{1}{12}
