Definition of Zero (of a function)
A zero of a function f(x) is a place where f(x)=0. In other words, it's a place where the graph of f(x) crosses the x-axis.
The function in the picture is f(x)=x2−1. It crosses the x-axis at x=1 and x=−1. So, it has zeroes at x=1 and x=−1.
Many people call the zeroes of a function the "roots" of a function. They mean exactly the same thing.
