f(x) is a polynomial function. Which one of the following statements is FALSE?

• f(x) has a derivative of zero when the graph of f(x) has a relative min or max.

• If the derivative of f(x) changes from positive to negative at some point, then the graph of f(x) has a relative minimum at that point.

• If the derivative of f(x) is always positive, then the graph of f(x) has no relative extrema.

• If the graph of f(x) is always increasing, then the derivative of f(x) is never negative.
