1. Graphing Quadratic Functions
Sign In
The axis of symmetry is the vertical line through the vertex.
Vertex: (1,1)
Axis of Symmetry: x=1
y-intercept: 4
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 ( 1, 1). We can see that the y-intercept of the graph is 4. Finally, the axis of symmetry is the vertical line through the vertex. In this case, the equation for the axis of symmetry is x= 1.
