Reflections
Vertical ReflectionsGiven any function ƒ(x):• ƒ(x) produces a reflection in the x-axis.y-coordinates are multiplied by (-1)
WARNING:
undoes whatever ƒ did.
Inverses: the inverse of any function ƒ(x) is (read as: "EFF INVERSE")
Horizontal ReflectionsGiven any function ƒ(x):• ƒ(-x) produces a reflection in the y-axis.x-coordinates are multiplied by (-1)
