Horizontal Reflection
A reflection in which a plane figure flips over horizontally. Note: A horizontal reflection has a vertical axis of reflection.
Horizontal Stretch or Compress
f (ax) stretches/compresses f (x) horizontally
A horizontal stretching is the stretching of the graph away from the y-axis.
A horizontal compression is the squeezing of the graph towards the y-axis.
If the original (parent) function is y = f (x), the horizontal stretching or compressing of the function is the function f (ax).
if 0 < a < 1 (a fraction), the graph is stretched horizontally by a factor
of a units.
if a > 1, the graph is compressed horizontally by a factor of a units.
if a should be negative, the horizontal compression or horizontal stretching of the graph is followed by a reflection of the graph across the y-axis.
