using calculus ?

$\large\color{black}{ \displaystyle f'(x)=? }$

jhannybean · Answer

So if you're given $x=3$ , your point of tangency will be $(3~,~ f(3)$

jhannybean · Answer

Then you find f'(x) which is your slope at the point of tangency, You find the slope at the point x=3, then use point slope form: $y-y_0 = f'(x) (x-x_0)$ to find the equation of the line.

Does that make any sense?

To help you use this site; this is not a "drop your homework and you get an answer"-site, as much as a great tool to interact and get help from people, learning what you are having problems with. "Teach a man to fish..." comes to mind. :)
