I'm not sure how to solve this:

Let the function f be defined by f(x) = x^2 - x. Which of the following has a negative value?
(a) f(-1)
(b) f(-1/2)
(c) f(0)
(d) f(1/2)
(e) f(1)

If anyone could EXPLAIN this--many thanks!! (I don't want the answer. Just a little help in understanding this, please.)
