Is is possible to calculate the growth-rate to a tangent in a graph? (like f(x)=x^2(adsbygoogle = window.adsbygoogle || []).push({});

I only know how to draw the line on the graph, but how do you calculate it if you know the point where you must draw the tangent?

For example: find the tangent of the point x=2 on a graph f(x)=x^2

How do you find the rate of growth?
