SEQUENCES OF TRANSFORMATIONS
A function involving more than one transformation can be graphed by performing transformations in the following order:
1.Horizontal shifting
2.Stretching or shrinking
3.Reflecting
4.Vertical shifting
EXAMPLE:
Use transformations of the
graph of 𝑓 𝑥 = 𝑥2 to graph
𝑔 𝑥 = 2 𝑥 + 3 2 − 1
