Using a graphing software, I'm trying to graph three things:(adsbygoogle = window.adsbygoogle || []).push({});

1. The function [tex]x^2[/tex].

2. It's derivative [tex]2x[/tex].

3. The tangent to the curve at point 3.

Now I know that that if I want to find the slope of the curve at point 3, I should substitute 3 into the derivative [tex]2x[/tex], which will give 6. What I want is the tangent line, not it's slope, at point 3. What equation should I input into the software to show the tangent to the curve at point 3? Please help.
