Calculate the derivative of a function using forward, backward, and central difference.

I need to calculate the derivative of f(x)= e^(-x) from x=0 to x=1 with an increment size of 0.1 using forward, backward, and central difference. I have never used matlab before and am struggling to figure it out.
