Answer

Domain: $(-\infty, \infty)$ Range: $[-4,\infty)$ Vertex: $(-3,-4)$ Axis: $x=-3$ Y-intercept: $(0,5)$ X-intercepts: $(-5,0)$ and $(-1,0)$

Work Step by Step

Domain: x can have value. Range: There are no points on the graph that have a y-value less than -4. Vertex: Can be seen on the graph. Axis of parabola: Has the same x-value as the vertex. Y-intercept: Substitute 0 for x and solve for y. Zeroes: Substitute 0 for y and solve for x.
