Homework Help: Mathmatica 7 Plotting Issue

  1. Sep 9, 2010 #1
    [solved] Mathmatica 7... Plotting Issue

    1. The problem statement, all variables and given/known data
    Plot the point (-3,f(-3)) on the same graph as f (using Mathmatica 7.)


    2. Relevant equations

    f(x)=x^3+4x^2-6

    3. The attempt at a solution

    A red box, or a graph without a box:
    Graphics[Point[{5, 10}], Plot[x^2, {x, -15, 15}, PlotRange -> {-10, 10}]]

    Depending on the order of Point and Plot.

    And thanks for any help!

    FIXED:

    I don't have it in front of me, but try to remember,

    mygraph = Plot[x^3+4x^2-6, {-15, 15}, PlotRange -> {-10, 10}]]
    mypoint=Graphics[Point[{3,#^3+#x^2-6&[-3]}]]
    Show[mygraph, mypoint]

    You can ignore the plotrange stuff.
