Calc problem

I have to match each polynomial formula with the correct Maclaurin polynomial below.  I am confused as to how to do this, so any help would be appreciated.

a) f(x) = (e^-x)-1
b) f(x) = 1/(x+1)
c) f(x) = 1/(1-x)
d) f(x) = (e^x) + sin(x)

1) 1 + x + x^2 + x^3
2) 1 + 2x + (X^2)/(2)
3) -x + (x^2)/(2) - (x^3)/(3)
4) 1 - x + x^2 - x^3
