The axis of symmetry is ݔ = __________. The vertex has the ݔ -coordinate __________. Substitute ݔ back in to find ݕ . The parabola opens up when ܽ ___ 0 and opens down when ܽ ___ 0 . The vertex is a _______________ when the parabola opens up and a __________________ when the parabola opens down. The y-intercept is located at ( 0 , ___). The parabola is vertically stretched when |ܽ| ___1 and is vertically compressed when |ܽ| ___1. You can find points on the parabola that are 1 unit to the right and left of the vertex if you use . STANDARD FORM ݕ = ܽݔ + ܾݔ + ܿ
Example 1: Graphing ______________ A] ݕ = 2ݔ − 8ݔ + 6 ܽ = ܾ = ܿ = Opens up or down? Axis of symmetry: Vertex: Is the vertex a max or min point? ݕ -intercept:

### What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
