One of the task in precalculus is finding zeros of the function - i.e. the intersection points with abscissa axis. Consider the graph of some function :

The zeros of the function
are the points
at which, as mentioned above, the graph of the function intersects the abscissa axis. To find the
*zeros of the function*
it is necessary and sufficient to
solve the equation:

The zeros of the function will be the roots of this equation. Thus, the zeros of the function are at the point .

Our online calculator, based on Wolfram Alpha system is able to find zeros of almost any, even very complicated function.
