### Estimating derivitives when given a graph?

I have a graph of f(x) and the question says
estimate f ' (-2), f '(-1), f '(0), and f ' (2)
Can someone explain step by step how to estimate it just for the 1st one

Look at the picture, and estimate the slope at the given points.

You look at the graph. You maybe draw a straight line that looks about right for the tangent, and compute it's slope. (Not being able to see the picture you're working with, it isn't really possible to give you precise instructions on how to look at it or make an estimate at the tangents you need.)
