x.params -- a string with the parameters for the function
x.color -- the color of the function in a color format This only applies to graphable functions
x.interval -- an array of values in an interval format. The size of the array is equal to the number of parameters.

The possible values for fntype are:
  • "user"
  • "xy"
  • "polar"
  • "para2d"

  outputString(x.fntype .. "\n")
  outputString(x.params .. "\n")
  outputString(x.color.r .. ", " .. x.color.g .. ", " .. x.color.b .."\n")
  for i = 1,#x.interval do
    outputString(x.interval[i].min .. ", " .. x.interval[i].max .. ", " .. x.interval[i].res .."\n")
  end
end
