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.
How do you find the intervals where a function is decreasing? a, b, c, and d, then the number line may look like this. Note: By the first derivative test we know that we have local maxima at a and d and local minimum at c. The first derivative test can be used for either type of critical value. 2.
