Graphing Parametric Relations in GeoGebra

You can graph the parametric relation x = t2 + 2t, y = t + 1 by entering (t2 + 2t, t + 1) in the input line below. If you would like to specify the range of t values graphed, use the CURVE command. To graph the part of the curve from t = –1 to t = 3, enter Curve(t2 + 2t, t + 1, t, –1, 3). Try it below!
