Parabola Characteristics

​What is the AXIS of SYMMETRY?

​What are the coordinates of the y-intercept?

​What are the coordinates of the x-intercepts?

​What are the coordinates of the VERTEX?

​Parabola: the shape of a quadratic function.

​Info from a Table

​What is the AXIS of SYMMETRY?

​What are the coordinates of the y-intercept?

​What are the coordinates of the x-intercepts?

​What are the coordinates of the VERTEX?

​EXAMPLE

Graph f(x) = x² + 2x - 5

​1 - Graph Vertex
2 - Graph other points

Graphing

If f(x) = x² + 4x - 5, graph the parabola.

(graph the vertex first, then one other point)
