The axis of symmetry is the x value of the vertex, so x=-2. The vertex is the highest or lowest point, in this case the lowest so it’d be (-2,-9). The domain is all possible x values, and since there’s no restrictions it’d be negative infinity to infinity. Since the graph goes upward, the range will be the lowest y value (-9) to infinity. The zeroes are (-5,0) and (1,0) since that’s where the graph crosses the x axis. And the graph is increasing because the two arrows are pointing in the upward direction
