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