Graph a Function

Plot a simple non-asymptotic function using Mathematica.

How-ToInstructor HelpWebAssign

This type of Mathematica graph is primarily used to plot lines, curves, and basic functions with or without asymptotes.

  1. Click Questions Create.

    The Question Editor opens.

  2. In Question, type your question.

    Use the answer placeholder string <_> to specify where the answer box should be displayed.

  3. Add WAPlot tags to the question, answer, or solution field of a question.

    If a WAPlot image is used in the answer field, the question mode must be multiple-choice, and there cannot be linebreaks in the WAPlot code. WAPlot images cannot be placed in assignment descriptions.

  4. <waplot type='MathematicaSyntax'> 
        Plot[
            x/2 - 1, 
            {x, -10,10}, 
            PlotRange->{{-10,10}, {-10,10}}, 
            AxesLabel->{x, y}, 
            AspectRatio->1, 
            PlotStyle->Directive[Blue, Thick]
        ]
    </waplot>

    Do not include "y =" before your expression. All expressions are assumed to be of the form "y =" and adding this will cause the solution to your function to be displayed as the y -axis label.
