Answer:
Vertex: (2,-1)
Y-intercept: (0,1)
Axis of symmetry: x=2
Explanation:
To find the vertex, look at the parabola's minimum or maximum point. In this case, the parabola has a minimum threshold. The fact that the minimum stops at is (2,-1), therefore giving you your answer for the vertex.
The y-intercept is where the parabola hits the y-axis. In this case, the parabola switches the y-axis at (0,1), giving you your answer.
Lastly, to find the axis of symmetry you need to look at the x value of the vertex and use set that numebr equal to x. Doing so gives you your axis of symmetry at x=2
