What are zeros of a function?

Zeros of a function are defined as the input values for which the function's output is zero. This means that when you substitute these specific input values into the function, the result, or output, will equal zero. In the context of a mathematical function, finding the zeros is crucial because they represent points where the graph of the function intersects the x-axis.

For example, if you have a function f(x) and you find that f(a) = 0 for some value a, then a is considered a zero of the function. This concept is pivotal in various applications, including solving equations, analyzing the behavior of functions, and understanding the roots of polynomials.

The other options relate to different aspects of functions but do not accurately define zeros.
