1. Graphing Quadratic Functions
Sign In
The axis of symmetry is the vertical line through the vertex.
Vertex: (0,0)
Axis of Symmetry: x=0
y-intercept: 0
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, 0). We can see that the y-intercept of the graph is 0. 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.
