(A) $1$. The parabola opens downwards,so the coefficient of $x^2$ must be negative. Thus,$a $2$. The $y$-intercept is the value of $y$ when $x = 0$. From the graph,the parabola intersects the $y$-axis below the origin,so $c $3$. The $x$-coordinate of the vertex is given by $x = -(-b) / (2a) = b / (2a)$.$4$. From the graph,the vertex lies to the right of the $y$-axis,so the $x$-coordinate of the vertex is positive,i.e.,$b / (2a) > 0$.$5$. Since $a $6$. Therefore,$a < 0, b < 0, c < 0$.

If the graph of $y = ax^2 - bx + c$ is as shown below,then the signs of $a$,$b$,and $c$ are:
