Objective: To construct graphs of linear and quadratic functions.
Tools: Insert Text

NoToolInstructions
1
Open GeoGebra. Use the View menu to display the coordinate axes.
2
Type y = - x + 4 to construct a line passing through A and B.
3
Type f(x) = 0.5x^2 - 4.5x + 9 to construct a parabola passing through points A and B.
4
To construct the intersection, type A = (2,2) and B = (5,-1) in the input bar and press the ENTER key after each equation.
5text.pngWe label the graphs. To label the graph of the quadratic function, click the Insert Text tool, and click on the Graphics view near the graph of the quadratic function to display the Text dialog box.
6
In the text dialog box, type f(x) = 0.5x^2 - 4.5x + 9 in the Edit text box, then click the Latex formula check box to check it, and then click the OK button. Notice what happens to the text.
7
Now, label the graph of the linear function and the coordinates of A and B with (2,2) and (5,-1) respectively.

  1. A parabola is the arrangement of all focuses in the plane equidistant from a given line (the conic segment indexes) and a given point not hanging in the balance (the core interest). The central parameter (i.e., the separation between the directrix and center) is along these lines given by , where is the separation from the vertex to the directrix or core interest. I like to do parabola and quardetic equations now I am looking to get Assignment Assistance anyone help me? The surface of insurgency got by turning a parabola about its pivot of symmetry is known as a parabola.
