ALG2 Graphing Quadratics
Since I am not in class today, Looking at examples on the board may not be the best to help you learn. Therefore I have created a set of videos to help you with your homework as well as understanding for this Unit.
Determining the vertex, axis of symmetry, domain and range give a quadratic in vertex form
Now that we know how to identify the key characteristics of a parabola in vertex form we will explore how to graph when it is in vertex form
Graphing a quadratic in vertex and labeling it’s parts
However what I wanted you to learn today when I was gone was how to graph a quadratic in vertex form by converting from standard form to vertex form using completing the square. I provided two examples to you on the board and will go over multiple examples in the next two videos.
Completing the square to convert a quadratic from standard form to vertex form, then find the vertes, axis of symmetry, domain and range
Now how to complete the square and graph
