Use reflections to sketch graphs of functions. Use compressions or stretches to sketch
graphs of functions.

Shifting Graphs
If c is a positive real number, then the graph of y= f(x) is shifted as follows:
1) vertical shift c units up f(x)+c 2) vertical shift c units down f(x) – c 3) horizontal shift c units to the right f(x-c) 4) horizontal shift c units to the left f(x+c)

Reflecting Graphs
1) Reflection in the x-axis -f(x) 2) Reflection in the y-axis f(-x)

Nonrigid Transformations
1) Vertical stretch cf(x), c >1 2) Vertical shink cf(x), 0<c<1 3) Horizontal shrink f(cx), c>1 4) Horizontal stretch f(cx), 0<c<1
