Vertex: (-1,1)
Axis of symmetry: x = -1
y-intercept: (0, 5)
The vertex is the curvy point on the graph. That curvy point’s on (-1,1), so that’s the vertex.
The axis of symmetry is the line that cuts the graph in half. As you can see, that line is x = -1, a vertical line that has all x values at -1.
The y-intercept is where the graph crosses the y-axis, which is at (0,5).
