You can create new objects (e.g. points, lines, functions) by either using the [i]Graphics Tools[/i] provided in the [i]Toolbar[/i], or by entering their equations and coordinates into the[i] Input Bar[/i].[br]

Enter the following equations and coordinates into the[i] Input[/i] [i]Bar[/i] to graph functions and points.

[table][tr][td][code]y = 3 x + 1 [br][/code][/td][td]Enter the equation [code]y = 3*x + 1[/code] into the[i] Input[/i] [i]Bar [/i]and press the [i]Enter[/i] key.[/td][/tr][tr][td][code]g(x) = x² + 2[br][/code][/td][td]Enter the function [code]g(x) = x^2 + 2[/code] into the [i]Input[/i] [i]Bar [/i]and press the [i]Enter[/i] key.[/td][/tr][tr][td][code]B = (2, 1)[/code][/td][td]Enter [code]B = (2, 1)[/code] into the [i]Input[/i] [i]Bar [/i]and press [i]Enter [/i]to create a new point.
