Transformations of QuadraticsDay 5: Quadratic Models Using Vertex Form

We will learn to determine the equation of a quadratic from a graph, or a table, using our knowledge of transformations. 

Aug 15­6:52 PM

Determine the equation of a quadratic relation in vertex form given its vertex is (1, ­27) and it passes through the point  (­1, ­15).  

State the key features:

 (vertex, axis of symmetry, minimum/maximum  value, x­ and y­intercepts, domain and range)

Aug 15­8:06 PM

Determine the equation of the parabola with vertex at (2, 4) and passes through the point (3,1).

Aug 15­8:07 PM

3. Determine the equation of the parabola shown in the following table of values.

Now we have two points on the curve, does this change your answer?

Oct 31­11:27 AM

With more data points the curve tells us more information. 

And like that, we’ve illustrated the fact that, while one point is enough to define a point, and while two points are enough to define a line, you need three points to define a parabola. 

Oct 31­11:36 AM

Key features of a quadratic relation

1. Parabola

2. Maximum/Minimum

3. Vertex

4. Axis of Symmetry

5. Zeroes
