Module 3 Lesson 17: Introduction to Transformations
The basic function for absolute values is: 𝑓(𝑥) = 𝑎|𝑥 − ℎ| + 𝑘
Let’s look at the following equations: 𝑓(𝑥) = |𝑥|, 𝑦 = 𝑓(𝑥) − 3, 𝑎𝑛𝑑 𝑦 = 𝑓(𝑥) + 2
Now let’s try a new transformation: 𝑓(𝑥) = |𝑥|, 𝑦 = 2𝑓(𝑥), 𝑎𝑛𝑑 𝑦 =1
2𝑓(𝑥)
Class practice: Graph the following expressions.
Let’s write the equations of m(x) and n(x).
