Answer 1

Since the arrowheads of the parabola are pointing downwards, the parabola opens downward.

To identify the axis of symmetry, determine the vertex of the parabola.

`(h,k)=(3,1)`

The formula for the axis of symmetry is as follows.

`\begin{gathered} x=h \\ x=3 \end{gathered}`

The x-intercept is the point where the graph intersects the x-axis, Thus, the x-intercepts are as follows.

`(2,0);(4,0)`

The y-intercept is the point where the graph intersects the y-axis. Thus, the x-intercept is as follows.

`(0,-8)`
