The zero point is the abscissa of the intersection of the image of the function y=f(x) and the X axis.

In mathematics, the zero point of the function y=f(x) is the real number solution which means that the function is equal to zero. In other words, the zero point is the real root of the equation f(x)=0. When the image of a function intersects the X axis, the abscissa of the intersection is the zero point of the function. This definition is based on the nature of the function and the geometric relationship of the image.
