Can a continuous function on a closed interval have no zeros? What is the role of derivatives in finding zeros (e.g., in optimization)?

The zero of a function is the x-value that makes the function equal to 0. In this tutorial, you'll learn about the zero of a function and see how to find it in ... Nov 7, 2015 ...
