Function zeros calculator

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 :

Plot of f(x) 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.
