Exercise 29 Page 100

The axis of symmetry is the vertical line through the vertex.

Vertex: (0,1)
Axis of Symmetry: x=0
y-intercept: 1

Practice makes perfect

To identify the vertex, axis of symmetry, and the y-intercept of the given parabola, let's start by labeling these features on our graph.

We can see above that the vertex is the point ( 0, 1). We can see that the y-intercept of the graph is 1. Finally, the axis of symmetry is the vertical line through the vertex. In this case, the equation for the axis of symmetry is x= 0.
