Reflecting Functions Over the X-Axis and Y-Axis

Reflecting Functions Over the X-Axis

  • the y value flips, y becomes -y, subsitute in -y for all instances of y
  • y = f(x) becomes -y = f(x), which is written as y = -f(x)

Reflecting Functions Over the Y-Axis

  • the x value flips, x becomes -x, substitute in -x for all instances of x
  • y = f(x) becomes y = f(-x)
