Lesson 4: Graphing Quadratics by Using Transformations
Recall: Quadratic functions can be graphed by using the properties given to us by the vertex form:
2
y  ax  h  k
We can use the different transformations to graph quadratic functions.
Complete the chart below and graph each equation on the same grid.

Remember, you can graph any function in vertex form by
applying any/all transformations to the key points of the
graph y  x 2 .
