  1. y = x^2+ 4
    raise graph up 4 units
  2. y = x^2 - 3
    lower graph 3 units
  3. y = (x + 4)^2
    shift graph left 4 units
  4. y = (x - 5)^2
    shift graph right 5 units
  5. y = 5x^2
    • stretch graph vertically times 5
    • y value multiplied by 5
  6. y = 1/2x^2
    • compress graph vertically by 1/2
    • y value multiplied by 1/2 (divided by 2)
  7. y = (4x)^2
    • compress graph horizontally by 1/4
    • x value multiplied by 1/4 (divided by 4)
  8. y = (1/2x)^2
    • stretch graph horizontally by 2
    • x value multiplied by 2
  9. y = -x^2
    reflects graph across x axis
  10. y = (-x)^2
