  1. Click here to use curve drawing program (in new browser window)
  2. To use the curve drawing program, first enter a formula for y in terms of x, in the form of entering a formula into a computer spreadsheet. Type the return key after the formula has been entered.
  3. Use * (asterisk) for multliplication; use ^ for exponents.
  4. Examples:
    1. y=2*x
    2. y=3*x^2
    3. y=4*x^3-297*x^2-598*x-915
    4. y=(x-3)*(x+5)
  5. Initially the graph will be scaled so that x and y values run from -50 to 50.
  6. If you click on the graph, it will zoom in twice as close, with the center of the graph at the point you click on.
  7. The small gray box at the upper left corner of the screen is a button that will reveal the zoom control buttons when you click on it. There are three zoom control buttons. The "zoom out" button will reverse the direction of zooming, so that each click will now zoom out instead of zooming in. The "zoom in" button will reverse the direction of zooming so that each click will again make the graph zoom in. The "to start" button will return the zoom level to where it was at the beginning.
  8. If you want to draw a graph of another curve, then close the window with this curve and click on the link here or at the top of the page to open a new window to draw another curve.
