Example #1

• graph these three areas
  • when y is less than 0, the square root function doesn't exist
  • when y is between 0 and 1, the square root function is slightly higher than the original function (when y = 0 and y = 1, the original function and the square root function share points)
  • when y is greater than 1, the square root function is lower than the original function (take the square root of the y value)
