Discriminant of A Differentiable Function
In differential topology, the discriminant of a differentiable function f is the same as the set of critical values of f. The discriminant in this sense is somewhat related to the discriminant of a polynomial; for example, if f(x)=ax2+bx+c is a quadratic (a≠0), then the critical value of f will be which is (up to a constant) equal to the discriminant of a quadratic polynomial.

Famous quotes containing the word function:
“Our father has an even more important function than modeling manhood for us. He is also the authority to let us relax the requirements of the masculine model: if our father accepts us, then that declares us masculine enough to join the company of men. We, in effect, have our diploma in masculinity and can go on to develop other skills.”
—Frank Pittman (20th century)
