About Sequence of Graphing Transformations:
In this section, we will continue to explore the topic of function transformations. Here, we will be challenged with finding the correct sequence of function transformations to go from a parent function f(x) to a given function g(x).
Test Objectives
- Demonstrate a general understanding of function transformations
- Demonstrate the ability to find the correct sequence of function transformations
#1:
Instructions: Describe the transformation from f(x) to g(x).
$$a)\hspace{.2em}$$ $$f(x) = |x|$$ $$g(x) = \frac{1}{2}|x| - 1$$
$$b)\hspace{.2em}$$ $$f(x) = x^2$$ $$g(x) = -2x^2 + 3$$

#2:
Instructions: Describe the transformation from f(x) to g(x).
$$a)\hspace{.2em}$$ $$f(x) = x^3$$ $$g(x) = (2x - 6)^3$$
$$b)\hspace{.2em}$$ $$f(x) = \sqrt{x}$$ $$g(x) = \sqrt{-\frac{1}{2}x + 1}$$

Instructions: Describe the transformation from f(x) to g(x).
$$a)\hspace{.2em}$$ $$f(x) = \sqrt{x}$$ $$g(x) = \frac{1}{2}\sqrt{\frac{2}{3}x - 1} + 1$$
$$b)\hspace{.2em}$$ $$f(x) = x^3 - x$$ $$g(x) = \frac{1}{3}(2x - 6)^3 - \frac{1}{3}(2x - 6) - 1$$
