Using a graphing software, I'm trying to graph three things:
1. The function x^2.
2. It's derivative 2x.
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 2x, 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.
