Answer
vertex: $(-2, -3)$
axis of symmetry: $x=-2$
minimum value: $-3$
range: $y\ge -3$
Work Step by Step
Use a graphing utility to graph the given function.
Refer to the graph below.
The vertex is the lowest or highest point on the parabola.
Notice that the vertex is at $(-2, -3)$.
The axis of symmetry of the graph is the line $x=h$ where $h$ is the $x$-coordinate of the vertex. Thus, the axis of symmetry is $x=-2$.
The parabola opens upward so the $y$-coordinate of the vertex is the minimum value.
Hence, the minimum value is $-3$.
The values of the function are all greater than or equal to $-3$.
Thus, the range is $y\ge -3$.
