Function Plotter

You ype in a function. It is plotted as a graph. You can manipulate the graph by changing its y-shift, x-shift, period and frequency. You can also interchange between dot and line plotting. It will dynamically update the graph when you change something about it. Please leve some feedback and tell me wha you think. Its not meant to be a huge project, just a one hour hing thatt'll maybe help somebody in the future.
