(adsbygoogle = window.adsbygoogle || []).push({}); [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.
