How to Find the Zeros of a Function. Three Methods: Finding Zeros by Factoring Finding Zeroes by Using the Quadratic Formula Finding Zeroes by Graphing. The zero of a function is a value of x that makes the value of function equal to zero. You usually try to find the zeros of a function to find an answer to a polynomial equation, such as x 2 + 4x +3 = 0. Follow these steps to learn several different ways how to find the zeros of a function. Ad.
The minimum or maximum of a function occurs when the slope is zero. Therefore, to find where the minimum or maximum occurs, set the derivative equal to zero. Continue with the sample problem from above: fâ²(x)=4xâ4{\displaystyle f^{\prime }(x)=4x-4}. 0=4xâ4{\displaystyle 0=4x-4}.
