Module 1: Function Transformations

 

Functions of the form y = f(xh) + k can be graphed quickly from y = f(x) using what you have learned so far about h and k. Watch Graphing with h and k to see an example of how to graph such a function.

 

 

This play button opens Graphing with h and k.

  1. Complete “Your Turn” from “Example 2” on page 9 of the textbook. Answer
  2. Complete questions 1.e., 3.c., 4.b., 15, and C1 on pages 12 to 15 of the textbook. Answer

You have explored how to determine characteristics of a graph from an equation; however, it is also possible to reverse this process and determine the equation of a graph if the graph of a similar function is known.

tip
In question 9.b. you were asked for the domain of a function. The domain can be represented in various ways. One method is to use set builder notation: {x|x ≥ 3, x ∈ R}, which is often abbreviated to x ≥ 3, x ∈ R or even x ≥ 3. Another common method is to use interval notation: (3, ∞). Both of these methods can also be used to describe the range of a function.
