Answer:

$\displaystyle (0, -1); maximum$

Step-by-step explanation:

First off, B is zero, so there is no phase shift, meaning that the vertex stays on the y-axis. Next, A is negative, so the parabola opens down, and whenever you have a parabola opening down, it does so at maximum. Finally, C represents our y-intercept, or in this case, our vertical shift. Our y-intercept is (0, −1), and so as our vertex, hence our answer.
