Examples, solutions, videos, and lessons to help High School students learn how to identify the effect on the graph of replacing f(x) by f(x) + k, kf(x), f(kx), and f(x + k) for specific values of k (both positive and negative); find the value of k given the graphs. Experiment with cases and illustrate an explanation of the effects on the graph using technology. Include recognizing even and odd functions from their graphs and algebraic expressions for them.

The following table gives the transformation rules for functions: Vertical and horizontal translations, Reflection over the x-axis and y-axis, Vertical and horizontal stretch, Vertical and horizontal compression. Scroll down the page for examples and solutions on how to use the transformation rules.

**Function Transformations: Horizontal and Vertical Stretches and Compressions**

This video explains to graph graph horizontal and vertical stretches and compressions in the form a*f(b(x-c))+d. This video looks at how a and b affect the graph of f(x).

af(x): a > 1, stretch f(x) vertically by a factor of a

af(x): 0 < a < 1, compress f(x) vertically by a factor of a

f(bx); b > 1, compress f(x) horizontally

f(bx); 0 < b < 1, stretch f(x) horizontally.**Function Transformations: Horizontal and Vertical Translations**

This video explains to graph graph horizontal and vertical translation in the form a*f(b(x-c))+d. This video looks at how c and d affect the graph of f(x).

f(x + c): shift f(x) c units left

f(x − c): shift f(x) c units right

f(x) + d: shift f(x) d units up

f(x) − d: shift f(x) d units down

**Functions Transformations: A Summary**

This video reviews function transformation including stretches, compressions, shifts left, shifts right, and reflections across the x and y axes.**Ex: Identify Function Translations using Function Notation**
